If the value of the action attribute is "none", no
action will be taken.
If the value of the action attribute is "remove", then
the element does not require a value.(The default value
of the action attribute is "remove").
The selected candidate attribute will be removed from
the DICOM object to make it anonymous.
If the value of the action attribute is "replace", then
the string value encoded in the attribute will be cast
into the corresponding type of the attribute and the
new value replaces the original.
If the value of the action attribute is "empty" , then the
attribute will be changed into zero length attribute (for future

If the value of the action attribute is "encrypt", then the string
value encoded in the action attribute will be replaced with an
encrypted value (for future use only).

Introduction
This schema defines the DICOM constraint document.
A DICOM constraint document defines rules
to check the conformance of a DICOM content with respect to
the DICOM standard and other organization-wide guidelines.
This XML schema document defines the XML schema constraining
constraint documents.
A constraint document defines one or more constraint rules.
A constraint rule is the unit of invocation for conformance checking.
At run time, a user may invoke a PL/SQL
or Java function to check the conformance of a DICOM content
with respect to a particular rule. Each invocable rule
is defined as a GLOBAL_RULE, which can reference other global
rules internally.
A constraint rule can be decomposed into individual predicates.
A predicate can be a logical statement, a relational statement
comparing values, a function call evaluation that returns a
Boolean type, or a reference to other predicate definitions.
Predicate definitions are recursive. A predicate can be a logical
statement, which includes the logical OR of two other predicates.
Each predicate can be a relational predicate. For example:
(patientName=="Joe Smith" AND patientSex=="M")
After being translated into a predicate, the preceding example becomes:
<PREDICATE>
<DESCRIPTION>An example to find an object that has
(patientName="Joe Smith" AND patientSex=="M")
</DESCRIPTION>
<LOGICAL operator="and">
<PREDICATE>
<RELATIONAL operator="eq">
<DICOM_ATTRIBUTE>00100010</DICOM_ATTRIBUTE>
<XML_VALUE>
<dt:PERSON_NAME>
<dt:NAME>
<dt:FAMILY>Smith</dt:FAMILY>
<dt:GIVEN>Joe</dt:GIVEN>
</dt:NAME>
</dt:PERSON_NAME>
</XML_VALUE>
</RELATIONAL>
</PREDICATE>
<PREDICATE>
<RELATIONAL operator="eq">
<DICOM_ATTRIBUTE>00100040</DICOM_ATTRIBUTE>
<XML_VALUE>
<dt:CODE_STRING>M</dt:CODE_STRING>
</XML_VALUE>
</RELATIONAL>
</PREDICATE>
</LOGICAL>
</PREDICATE>
Constraint macros can be used to simplify the definition of
complex constraint rules. Constraint macros follow the same predicate
definition grammar as constraint rules. The operands in
constraint macros can be variables rather than fixed values, as they are
in constraint rules. The variables in a macro are substituted when the
macro is invoked. For example, you can define a macro to compare
patient names ( patientName == $NAME ). When this macro is invoked,
the parameter NAME is assigned the value "Joe Smith" and the macro is
transformed into the predicate:( patientName == "Joe Smith").
As another example, you can define a macro to check if a DICOM attribute
is a code sequence attribute. A code sequence attribute must contain the
mandatory child attributes, code value and code scheme. This macro
checks whether the specified code sequence attribute contains these
mandatory child attributes.
<GLOBAL_MACRO name="CSMacro">
<DESCRIPTION>
A subset of Code Sequence Macro defined in DICOM standard,
PS3.3-2007, Table 8.8-1

<BOOLEAN_FUNC operator="notEmpty">
<DICOM_ATTRIBUTE>${CodeAttr}.00080102
</DICOM_ATTRIBUTE>
</BOOLEAN_FUNC>
</PREDICATE>
<!-- other predicates follow -->
</GLOBAL_MACRO>
You can separate a constraint definition into multiple files.
Each file defines one or more constraint rules or macros.
A file can import the macros and constraint rules that are
defined in a difference file. You must specify the set of
external rules or macros before referencing them in a file.
EXTERNAL_RULE_INCLUDE and EXTERNAL_MACRO_INCLUDE
statements serve this purpose.

<xs:documentation>A predicate group is the logical AND
of a collection of predicates or predicate groups.
Each predicate group has a name that is unique within
its parent. Any other predicates can reference
this predicate group by its name. The value of the reference
is the Boolean of the predicate group.
Optionally, a predicate group can contain a set of
predicate definitions. These definitions are not part of the
logical AND component of the predicate group, but they
are meant to be referenced within the predicate group.
A predicate group has an optional action element that
specifies what action to take when the predicate evaluates to true
or false.

The second operand must be a Java regular expression

attribute tag. The tag should identify an attribute
that belongs to one of the following value representation
types:
AE, AS, AT, CS, DA, DT, LO, LT, PN,
SH, ST, TM, UI and UT
Note that the operands must be compatible with each other
when a predicate invokes relational operator. For example,
(patientAge > 005M) is a valid predicate. But
(patientAge > "Joe Smith") is not a valid predicate, because
the operand "Joe Smith" cannot be cast into an instance
of the patient age attribute.

The current values for this operator
are: "notEmpty", "occurs", "true", and "false".
"occurs" takes a single operand ATTRIBUTE_TAG,
and returns true if an attribute matching the tag exists. (The
attribute value can be an empty string or null. For example,
a DICOM type 2 attribute may be empty.); Otherwise, it returns
false.
"notEmpty" takes a single operand ATTRIBUTE_TAG.
It returns true if an attribute matching the tag exists in

Introduction
This schema defines the DICOM standard data types that are used
by all other DICOM XML schema definitions.
Naming conventions:
All DICOM value representation (VR) types are named with a
2-character string, such as "AE" and "CS".
All DICOM attribute type definitions are named as VR_ATTR_T,
where VR is replaced by the attribute's 2-character VR.
Note that each item of a sequence type (SQ) is of DATASET_T type.
The DATASET_T type can recursively contain more attributes.
The element name of an attribute is its value representation (VR)
name. Oracle uses value representation names defined
by the DICOM standard part 5. The element
name to VR mappings are:
APPLICATION_ENTITY --- AE
AGE_STRING --- AS
ATTRIBUTE_TAG --- AT
CODE_STRING --- CS
DATE --- DA
DECIMAL_STRING --- DS
FLOAT_SINGLE --- FL

<xs:documentation>DICOM Value representation Age String.
The age string can be expressed either in DICOM string
format, or in number of days. When metadata is extracted
from a DICOM object, both elements will be populated.
XML documents can represent age by either format.
Age in number of days is converted into an age string when
XML metadata is encoded into a DICOM object.
To convert from age string into the number of days:
365 * number_of_year or 31 * number_of_month.
Because AGE_STRING is mandatory, it is not necessary to
convert from the number of days into an age string.

<xs:documentation>
Attribute group type (ATTR_GRP_T) is used by all DICOM attribute
definitions. It defines XML attributes that are used by all DICOM
attribute types.
The "tag" attribute defines DICOM attributes in little-endian encoding.
The "definer" attribute specifies the organization that has
created the attribute. By default, all DICOM standard
attributes have the definer name "DICOM".
The "name" attribute specifies the canonical attribute name
as defined by the data dictionary. For example, in
an XML metadata schema definition, you can choose a tag
PATIENT_DATE_OF_BIRTH or "DOB" for DICOM attribute
(0010,0030), but its name attribute should match that of the
DICOM standard: "Patient's Birth Date".
The "truncated" attribute takes a Boolean value. If it is true,
it indicates that the original length of the DICOM attribute
exceeds the maximum length allowed for this XML value;therefore,
it is truncated in XML. When this attribute is true,
xsi:nill="true" for this attribute.
Optionally, the "rawValue" attribute can be used to store
values that do not conform to the DICOM standard. The
associated attribute "byteOrderLE" specifies the byte order
of the byte stream for the "rawValue" attribute.
"offset" and "length" are Oracle-reserved attributes.

Attribute definer is identified by its name and UID.
In Oracle's implementation, the DICOM standard is given the
definer name "DICOM" and the UID "1.2.840.10008.1".
All DICOM standard attributes are given the definer name "DICOM".
Users can introduce private attributes of their own and encode them
in an XML document. These private attributes are identified
with the definer's name and UID. Oracle recommends that all DICOM
private attributes be associated with a UID-qualified name.

The DICOM value locator type identifies a particular
DICOM attribute by "xxxxxxxx(definer)", where
"xxxxxxxx" is the attribute tag and "definer" is the
attribute definer, which can be the DICOM standard
(DICOM) or other private sources.
A locator path can also identify a particular
descendent of a container type attribute (SQ).
The n-th item of a sequence attribute is denoted by
"xxxxxxxxx(definer)[n]".
By default, the definer suffix "(definer)" can be
omitted if the attribute is a DICOM standard tag.
The index "n" of an item address "[n]" must be a
positive integer. The item address suffix can be
omitted if the item it pointed to is the first item
of a sequence.
For example, 00080096.00401101.00080100 is the code
that identifies the first referring physician. The
above value locator is equivalent to:
00080096(DICOM)[1].00401101(DICOM)[1].00080100(DICOM)

<xs:documentation>
VALUE_LOCATOR_MACRO_T is similar to the value locator
type, except that it permits the use of a macro within
the locator string.
So, the macro locator string can be:
${TAG}(DICOM)[2].00080100
This string indicates the code value (0008,0100) of the second
item of a sequence attribute identified by ${TAG}.
The macro parameter TAG can be replaced by a
compatible attribute tag (code sequence attribute)
later.

DICOM value representation types.
In the DICOM standard, VR for certain attributes
is defined as "other word or byte", "US or SS", or
"See Note". Oracle has extended the list of VR types and
introduced OWB (for "other word or byte"),
USS (for "US or SS"), and
EXP (where VR definition does not apply).
When an attribute of USS type is encoded into XML, it is
automatically encoded as a signed short type.
When an attribute of OWB type is encoded into XML, it is
automatically encoded into other word type.
An example of an attribute with VR type of EXP is
the sequence item (FFFE, E000).
For compatibility with future DICOM releases, if a new
DICOM VR is introduced by the DICOM standard,
users can mark such attributes as type "EXT??",
where "??" should be replaced by the new VR name.

This schema defines the DICOM (XML) mapping document.
It defines how each DICOM attribute maps to an element of the
DICOM metadata document.
The mapping document is used by the metadata encoder to produce
a DICOM metadata document. Each DICOM attribute is identified by
a 4-byte hexadecimal attribute tag. Each DICOM attribute is mapped
to an element of the XML metadata document designated by the PATH
element. By default, a DICOM attribute can be null and is optional.

are defined by the MAPPED_XPATH elements
of an XML mapping document. This element
specifies a relative path from ROOT_ELEM_TAG.
For example, to map a DICOM attribute (0010,0010) to

specify the following
The ROOT_ELEM_TAG element value is "DICOM_METADATA".
The MAPPED_ELEM element value is "PATIENT" and

A MAPPED_PATH element contains attribute tag and
path pairs.
An attribute tag uniquely identifies an attribute within the
data dictionary. Wildcards are not allowed in an attribute
tag specification in this release.
The path consists of slash "/"-concatenated element names.
A path specifies the destination of an attribute in the
DICOM XML metadata document. The mapped path
is the relative path from ROOT_ELEM_TAG and
MAPPED_ELEM. The absolute path is:
"${ROOT_ELEM_TAG} / ${MAPPED_ELEM} /
${MAPPED_PATH}".
The optional attribute "occurs" specifies whether the
attribute must exist in the original DICOM content.
(The attribute tag must exist, but the attribute value
can be an empty string, for example, a DICOM type 2
attribute.)
The optional attribute "notEmpty" specifies
whether the attribute must have a value in
the original DICOM content (type 1 in DICOM terms).
Depending on the run-time preferences, if the
above "occurs' or "notEmpty" condition is not
met, an error may be thrown at run-time.
The optional attribute "writeTag" specifies whether to
add the attribute "tag" when writing the element.
The tag attribute is of type "dt:AT". The value of this
attribute is the DICOM attribute tag in little-endian
encoding.
The optional attribute "writeDefiner" specifies whether
to add the attribute "definer" when writing the element.
The definer attribute is of type "dt:LO". The value of
this attribute is the same as the definer attribute of
ATTRIBUTE_TAG element of the mapping document.
The optional attribute "writeName" specifies whether
to add the attribute "name" when writing the element.
The name attribute is of type "dt:SHORT_STRING_T".
The value of this element is the attribute name
defined by the data dictionary.
The optional attribute "writeRawValue" specifies whether
to add the attribute "rawValue" when writing the element.
The raw value attribute is of type "xs:hexBinary".
This attribute only occurs when there is a parsing error
for this attribute and no XML value can be extracted for
the element. The value of this attribute is the
hexadecimal dump of the original byte stream.

Introduction
This schema defines the DICOM standard data types that are used
by DICOM metadata schemas.
Naming conventions:
All DICOM value representation (VR) types are named with a
2-character string, such as "AE" and "CS".
All DICOM attribute type definitions are named as VR_ATTR_T,
where VR is replaced by the attribute's 2-character VR.
Note that each item of a sequence type (SQ) is of DATASET_T type.
The DATASET_T type can recursively contain more attributes.
The element name of an attribute is its value representation (VR)
name. Oracle uses value representation names defined
by the DICOM standard part 5. The element
name to VR mappings are:
APPLICATION_ENTITY --- AE
AGE_STRING --- AS
ATTRIBUTE_TAG --- AT
CODE_STRING --- CS
DATE --- DA
DECIMAL_STRING --- DS
FLOAT_SINGLE --- FL
FLOAT_DOUBLE --- FD
INTEGER_STRING --- IS
LONG_STRING --- LO
LONG_TEXT --- LT
OTHER_BYTE --- OB
OTHER_FLOAT --- OF
OTHER_WORD --- OW
OTHER_WORD --- OWB
PERSON_NAME --- PN
SHORT_STRING --- SH
SIGNED_LONG --- SL
SEQUENCE --- SQ
SIGNED_SHORT --- SS
SHORT_TEXT --- ST
TIME --- TM
UNIQUE_ID --- UI
UNSIGNED_LONG --- UL
UNKNOWN --- UN
UNSIGNED_SHORT --- US
SIGNED_SHORT --- USS
UNLIMITED_TEXT --- UT
EXTENDED_TYPE --- EXT
EXCEPTION_TYPE --- EXP
The VR types "OWB', "EXT", "EXP" and "USS" are
Oracle-defined extensions.
Please refer to the individual data type documentation for
more explanation.

The age string can be expressed either in DICOM string
format, or in number of days. When metadata is extracted
from a DICOM object, both elements will be populated.
XML documents can represent age by either format.
Age in number of days is converted into an age string when
XML metadata is encoded into a DICOM object.
To convert from age string into the number of days:
365 * number_of_year or 31 * number_of_month.
Because AGE_STRING is mandatory, it is not necessary to
convert from the number of days into an age string.

<xs:documentation>
Attribute group type (ATTR_GRP_T) is used by all DICOM attribute
definitions. It defines XML attributes that are used by all DICOM
attribute types.
The "tag" attribute defines DICOM attributes in little-endian encoding.
The "definer" attribute specifies the organization that has
created the attribute. By default, all DICOM standard
attributes have the definer name "DICOM".
The "name" attribute specifies the canonical attribute name
as defined by the data dictionary. For example, in
an XML metadata schema definition, you can choose a tag
PATIENT_DATE_OF_BIRTH or "DOB" for DICOM attribute
(0010,0030), but its name attribute should match that of the
DICOM standard: "Patient's Birth Date".
The "truncated" attribute takes a Boolean value. If it is true,
it indicates that the original length of the DICOM attribute
exceeds the maximum length allowed for this XML value;therefore,
it is truncated in XML. When this attribute is true,
xsi:nill="true" for this attribute.
Optionally, the "rawValue" attribute can be used to store
values that do not conform to the DICOM standard. The
associated attribute "byteOrderLE" specifies the byte order
of the byte stream for the "rawValue" attribute.
"offset" and "length" are Oracle-reserved attributes.

The DICOM value locator type identifies a particular
DICOM attribute by "xxxxxxxx(definer)", where
"xxxxxxxx" is the attribute tag and "definer" is the
attribute definer, which can be the DICOM standard
(DICOM) or other private sources.
A locator path can also identify a particular
descendent of a container type attribute (SQ).
The n-th item of a sequence attribute is denoted by
"xxxxxxxxx(definer)[n]".
By default, the definer suffix "(definer)" can be
omitted if the attribute is a DICOM standard tag.
The index "n" of an item address "[n]" must be a
positive integer. The item address suffix can be
omitted if the item it pointed to is the first item
of a sequence.
For example, 00080096.00401101.00080100 is the code
that identifies the first referring physician. The
above value locator is equivalent to:
00080096(DICOM)[1].00401101(DICOM)[1].00080100(DICOM)

VALUE_LOCATOR_MACRO_T is similar to the value locator

This string indicates the code value (0008,0100) of the second

The macro parameter TAG can be replaced by a

DICOM value representation types.
In the DICOM standard, VR for certain attributes
is defined as "other word or byte", "US or SS", or
"See Note". Oracle has extended the list of VR types and
introduced OWB (for "other word or byte"),
USS (for "US or SS"), and
EXP (where VR definition does not apply).
When an attribute of USS type is encoded into XML, it is
automatically encoded as a signed short type.
When an attribute of OWB type is encoded into XML, it is
automatically encoded into other word type.
An example of an attribute with VR type of EXP is
the sequence item (FFFE, E000).
For compatibility with future DICOM releases, if a new
DICOM VR is introduced by the DICOM standard,
users can mark such attributes as type "EXT??",
where "??" should be replaced by the new VR name.

DESCRIPTION
VALUE
The allowed values for the PARAMETER element of a
PREFERENCE_DEF entry and its corresponding
VALUE element are as follows:
PARAMETER: XML_SKIP_ATTR
VALUE: an integer type (default 512, 128~ 32767)
DESCRIPTION: When encoding a DICOM attribute into XML, skip
attributes whose (child) XML element sizes (in bytes) are
larger than XML_SKIP_ATTR.
If an attribute is of simple type, this limit applies to the
whole attribute.
If the attribute type is SQ, this limit applies to its child
items.
For example, if an attribute is of type SQ and it contains
child items of type OB, the limit applies to
each child instance of type OB.
The smallest value allowed for this parameter is 128.
PARAMETER: AVG_ATTR_NUM
VALUE: an integer type (default 200, 20~2000)
DESCRIPTION: The average number of root-level attributes per
DICOM object. This is a hint to the DICOM implementation.
Finding the optimal value for a database helps improve storage
efficiency and performance. Too large a value may lead to wasted
memory, and too small a value may lead to poor performance. An
ideal value is one where most (suggested 95%) DICOM images
have less than $VALUE number of attributes.
The smallest value allowed for this parameter is 20.
The largest number allowed for this parameter is
the total number of not retired standard attributes defined.
PARAMETER: CONFORMANCE_LEVEL
VALUE: enum { leastConform, ignoreException(default), mostConform}
DESCRIPTION:
The option "leastConform" means that all functions try to
maximize the processing of a DICOM object and ignore
any errors and exceptions.
"ignoreException" means that all functions ignore the
types of exceptions given in the parameter "IGNORED_EXP_LIST".
The default set of ignored exceptions includes: MISSING_ATTR,
INVALID_LENGTH, MISSING_MAGIC, MISSING_HEADER, INVALID_VR, and
INVALID_VM.
"mostConform" means that all functions throw an exception
if a DICOM object contains nonconformant content. This does
not include backward compatibility cases allowed by
the DICOM standard.
Note: By choosing an option other than "mostConform",
you risk accepting invalid DICOM objects, possibly getting
incorrect results. In this case, Oracle recommends setting the
LOGGING_LEVEL parameter to "warning" or a more detailed level,
and then examining the log file for possible errors.
PARAMETER: IGNORED_EXP_LIST
VALUE: EmptySpace-separated exception names from the
following list:
{MISSING_MAGIC, MISSING_HEADER, MISSING_ATTR,
FAULTY_VALUE, INVALID_LENGTH,
INVALID_VM, INVALID_VR, UNSUPPORT_VALUE,
UNDEFINED_VALUE, NOT_AN_IMAGE}
Default: {MISSING_ATTR INVALID_LENGTH MISSING_MAGIC
MISSING_HEADER INVALID_VR INVALID_VM}.
DESCRIPTION: This parameter is only effective when the value of
the CONFORMANCE_LEVEL parameter is "ignoreException". If
this is the case, the exceptions in the ignore exception list are
ignored at run time. However, if the LOGGING_LEVEL parameter
is set to "warning" or a more detailed level, the exception is
logged. The program continues and skips the part
of the DICOM object that has triggered an exception.
These exceptions are defined as follows:
MISSING_MAGIC: a DICOM object does not contain the file
magic number "DICM".
MISSING_HEADER: a DICOM object does not have the file
meta header (not conformant to the DICOM standard part 10).
MISSING_ATTR: a DICOM object does not have the mandatory
attributes (type 1) required by the DICOM standard.
FAULTY_VALUE: a DICOM object has attribute values
that lead to parsing errors.
INVALID_LENGTH: a DICOM object contains a length value that
is not consistent with the DICOM encoding rules or a length
that is not permitted by the DICOM data dictionary.
INVALID_VM: an attribute of a DICOM object has an invalid Value
Multiplicity value (not consistent with the dictionary definition).
INVALID_VR: an attribute of a DICOM object has an invalid Value
Representation value, which can either conflict with the data
dictionary or has not been defined by the data dictionary.
UNSUPPORTED_VALUE: a DICOM object contains attribute
values that are outside of the supported range;
for example, an unsupported pixel representation value.
UNDEFINED_VALUE: a DICOM object contains attribute
values that are not defined by the data model; for example,
an undefined transfer syntax UID, an undefined SOP
class UID, and so on.
NOT_AN_IMAGE: When an image content processing function
is invoked on a DICOM object, if the object's SOP class UID is
defined but its classification is not "storageClass", or its
content type is not "image", an exception is thrown. It may
mean that the UID definition document is not up-to-date. An
administrator can update the document to define the
SOP class UID as a "storageClass" of "image" type.
PARAMETER: OUTPUT_RAW_VALUE
VALUE: an integer value (default to 0, no output) (-1 ~ 32767)
DESCRIPTION: What to output in an XML metadata document
when the parsing of a DICOM object fails. The base64 encoding
of the attribute's byte value can be returned in the rawValue
attribute of a DICOM XML element. The VALUE element specifies
the maximal length allowed for the rawValue attribute.
If $VALUE == -1, (not recommended), the entire attribute up to 32k
is saved in the rawValue attribute in base64 encoding.
If $VALUE == 0, an empty string is saved in the rawValue
attribute (recommended for production systems).
If $VALUE == N > 0, only the first N bytes of the attribute are
saved in the rawValue attribute.
A nonzero value for this parameter is useful for debugging
purposes. For a production system, do NOT pick a value
larger than 64. The value -1 should never be used outside of
a development environment.
PARAMETER: LOGGING_LEVEL
VALUE: enum {debug, conformance, warning(default), error, none }
DESCRIPTION: The logging level, if ordered by the level of
detail from the most to the least is: "debug", "conformance",
"warning", "error", and "none".
"debug" means extensive logging of all steps; it should
only be used for debugging purposes.
"conformance" means to log all nonstandard conformance
problems that are discovered. In general, nonconformance is very
common for a DICOM object repository containing DICOM
objects from different sources, for example, a hospital or an imaging
center. This logging level may lead to large log files for
most scenarios, and lower performance.
"warning" means to log all recoverable messages that require
operator attention. For example, if a user invokes an
image processing function on a DICOM object and
Oracle does not recognize this DICOM object as an image,
a warning message is logged stating that this DICOM object
is not defined as an image. The processing of the image
content may continue if the CONFORMANCE_LEVEL
parameter is set to ignore "NOT_AN_IMAGE" exception.
"error" means to log only irrecoverable messages.
"none" means that logging is disabled.
Note: Do not use the "debug" option for a deployed system.
It adds significant overhead and slows down all
DICOM related functions.
PARAMETER: VALIDATE_METADATA
VALUE: Boolean{true, false(default)}
DESCRIPTION: The DICOM function extractMetadata takes a
mapping document as an input parameter. A mapping document
contains a namespace parameter (which can be empty). If an
XML schema is registered at this namespace, and the value of
the VALIDATE_METADATA parameter is true, the extractMetadata
function validates the resulting XML document against the
designated schema.
If the value of this parameter is false, the resulting XML document
is not validated.
PARAMETER: EXP_IF_NULL_ATTR_IN_CONSTRAINT
VALUE: Boolean{true(default), false}
DESCRIPTION: A DICOM object may not contain certain attributes
that are used in a constraint predicate. The object may
contain an attribute, but its value is empty. Both cases
result to a null value attribute. So a constraint
predicate involving this attribute has a null
parameter value such as (null== MY_VALUE).
If this preference parameter is set to true,
an exception is thrown if the first occurrence of a
a null-value attribute is not guarded by the "notEmpty"
Boolean function. If this parameter is set to false,
no exception is thrown and the predicate evaluates to
false. To avoid confusion, it is always better to guard an
attribute with "notEmpty" Boolean functions before using
the attribute value in a predicate.

DOCUMENT_HEADER is an optional header to specify the

for more information.
ATTRIBUTE_DEFINERS specify the owner of each
private attribute. See dt:ATTR_DEFINER_T for more
information.
A private dictionary contains one or more private attribute
definitions.
Each private attribute specification takes a tag specification,
a name, a value representation type, a value multiplicity
type, and a retired flag. See dt:VR_T dt:VM_T for the allowed
values for the value representation and value multiplicity elements.
Note: Private attribute tags allow three specification types.
The tag can be a 4-byte hexadecimal number, a
wildcard type such as "0039xx01", or a range type such
as "0039xx01~0041xx01".
Multiple attribute definitions cannot be associated with
the same definer-tag pair in a dictionary. For example, a simple
attribute definition ("oracle", 60100010) matches a wildcard
attribute ("oracle", 60xx0010), they cannot coexist in the private
dictionary. Similarly, a range attribute definition ("Oracle", {6000-60FF})
overlaps a range attribute definition ("Oracle", {6010-6020}), they
cannot coexist in the private dictionary. As a rule, an attribute
must not match two entries in the dictionary.

DOCUMENT_HEADER is an optional header to specify the

for more information.
ATTRIBUTE_DEFINERS specify the owner of each
attribute. See dt:ATTR_DEFINER_T for more
information. All DICOM standard attributes must have
definer name "DICOM" and UID "1.2.840.10008.1".
A standard dictionary contains one or more standard attribute
definitions.
Each standard attribute specification takes a tag specification,
a name, a value representation type, a value multiplicity
type, and a retired flag. See DICOM P3-6 2007 for a
description of these elements. See dt:VR_T dt:VM_T for the allowed
values of value representation and value multiplicity elements.
Note: Wildcard character "x" can be used to specify
standard attribute tags (for example, 60xx0010 for overlay rows).
Multiple attribute definitions must not be associated with
the same tag in a standard dictionary. For example, the
attribute definition 60100010 matches the wildcard
attribute 60xx0010, they cannot coexist in
the dictionary. As a rule, an attribute must not match two
entries in the dictionary.

UID_DEF (classification, isLE?, isEVR?, isCompressed?,retired?, contentType?)+
UID
NAME
DESCRIPTION?
A UID_DEF entry describes a UID value.
The mandatory classification attribute specifies what
a UID is. Its value can be "transferSyntax", "storageClass",
"frameOfRef", "ldapOID", "entityID", or "other".
"transferSyntax" means that the UID identifies transfer syntax.
"storageClass" means that the UID identifies a storage class.
"frameOfRef" means that the UID is a well-known frame of reference.
"ldapOID" means that the UID is an LDAP OID.
"entityID" means that the UID identifies an entity, which can be
an organization or a device manufacturer.
"other" means that the UID does not fall into any of the previous
categories.
For entries that have a classification type of
"transferSyntax", the attributes "isLE", "isEVR", and
"isCompressed" further define the transfer syntax. These
attributes are ignored for all other classification types.
The "isLE" attribute specifies whether the binary stream
will be encoded with little-endian byte order(defaults to true).
The "isEVR" attribute specifies whether the binary stream
will use the explicit VR encoding rule (defaults to true).
The "isCompressed" attribute specifies whether the
transfer syntax means that the data content is compressed
(defaults to true).
If an entry has a classification type of "storageClass",
the "contentType" attribute further specifies the primary
content of a DICOM object belonging to this class.
The value of this attribute can be "image", "waveform",
"report" or "other".
"image" can be single-frame, multi-frame images, or video.
"waveform" can be ECG, EEG, or any other 1D signal.
"report" means a structured report.
"other" means overlay, GSPS, KO, or any other object types that
do not belong to the previous categories.
For example "Ultrasound Multi-frame Image Storage" SOP
class has a UID of "1.2.840.10008.5.1.4.1.1.3.1". Its
primary content is image.
