This chapter discusses tagged content and other content topics.
The SCCCA_BEGINTAG and SCCCA_ENDTAG content types are used to tag or delimit other content for a particular purpose. This can be especially useful when searching for specific document property values like the author or title of a document. It can also be used to separate subdocument text like headers, footers, and footnotes from the main document text. Tagged text may be nested inside other tagged text, and tags may overlap each other.
Though most tag types are not particularly useful to developers, the Data Access technology provides all of the tag types rather than make a judgment as to usability. Each is briefly described below.
This section lists the applicable parameters and corresponding values.
dwType
SCCCA_BEGINTAG: Beginning of tagged content
SCCCA_ENDTAG: End of tagged content
dwSubType: Tag type - see "Tag Types" on page 7-1
dwData1: Additional ID - see "Document Property IDs" on page 7-3 or "Mail Field IDs" on page 7-6

When dwSubType is SCCCA_DOCUMENTPROPERTY, dwData1 will be one of the values listed in the header file sccca.h. The following section, Document Property IDs, lists many of the common document property types. Any content generated between the begin and end tag defines the value of the document property.
When dwSubType is SCCCA_EMAILFIELD, dwData1 will be one of the values in "Mail Field IDs" on page 7-6, and any content generated between the begin and end tag defines the value of the email field.
The following is a list of document property IDs.

A SCCCA_COMMENTREFERENCE is placed in the actual location of the comment. The body of the comment may appear elsewhere and will be tagged with a SCCCA_BEGINTAG of type SCCCA_SUBDOCTEXT and will have the same Id as the SCCCA_COMMENTREFERENCE.
dwType: SCCCA_COMMENTREFERENCE
dwSubType: None
dwData1: Type of the comment reference anchor. SCCCA_COMMENT_PARAGRAPH, SCCCA_COMMENT_CELL, SCCCA_COMMENT_SLIDE, or SCCCA_COMMENT_VECTORPAGE.

This section lists the applicable parameters and corresponding values.
dwType: SCCCA_GENERATED
dwSubType: Possible values include the following:
SCCCA_DOCUMENTTEXT: Regular document text is returned with this subtype.
SCCCA_SPECIALTEXT: Used to return text elements that are manufactured by the technology due to special formatting attributes.
SCCCA_REVISIONDELETE: Will be OR-ed with either SCCCA_DOCUMENTTEXT or SCCCA_SPECIALTEXT when text has been deleted from the final version of a document as a result of a revision.
SCCCA_URLTEXT: Text for the Link Location part of a URL.
SCCCA_XMPMETADATA: Text from embedded XMP metadata.
dwData1: Number of characters provided in pDataBuf
dwData2: Original character set of the text in pDataBuf
dwData3: Reserved
dwData4: Reserved
pDataBuf: Text buffer. Filled with one or more single- or double-byte characters.
This content type is provided to allow the developer to access the content of SubObjects, like embedded graphics or objects in an archive. The SubObject can then be opened by DAOpenDocument, filling the IOSPECSUBOBJECT or the IOSPECARCHIVEOBJECT parameter with one of the following values:
dwType: SCCCA_OBJECT
dwSubType: Set to SCCCA_EMBEDDEDOBJECT (0) if the sub-object is an embedding or is set to the type of node if the object is from an archive. Possible values include the following:
SCCCA_EMBEDDEDOBJECT
SCCCA_ARCHIVEITEMCONTAINER
SCCCA_COMPRESSEDFILE
SCCCA_MESSAGE
SCCCA_CONTACT
SCCCA_CALENDARENTRY
SCCCA_NOTE
SCCCA_TASK
SCCCA_JOURNALENTRY
SCCCA_ATTACHMENT
dwData1: The internal SubObject identifier or a node identifier.
dwData2: Stream identifier for an alternate graphic.
dwData3: Stream identifier for an OLE object if one exists. Otherwise, it is CA_INVALIDITEM.
dwData4: Reserved
pDataBuf: Not used
This content type contains only the sheet name (worksheet in a spreadsheet, slide in presentation, etc.). This content is not optional. It is always created if the information is present. Of course, the client can ignore this text when it is returned.
This section lists the applicable parameters and corresponding values.
dwType: SCCCA_SHEET
dwSubType: Reserved
dwData1: The length of the name in pDataBuf in characters.
dwData2: The original character set of the name in pDataBuf.
dwData3: Reserved
dwData4: Reserved
pDataBuf: Points to the sheet name in whatever output character set has been requested.
The SCCCA_STYLECHANGE content type is used to indicate changes in style information. This style information can be used to delimit particularly interesting content.
This section lists the applicable parameters and corresponding values.
dwType: SCCCA_STYLECHANGE
dwSubType: Possible values include the following:
SCCCA_PARASTYLE: pDataBuf indicates the name of the style.
SCCCA_HEIGHTANDSPACING: When dwSubType is SCCCA_HEIGHTANDSPACING, dwData1 can be SCCCA_HEIGHT (dwData2 represents the new character height), SCCCA_SPACING (dwData3 represents the new line spacing) or both of these values OR-ed together.
SCCCA_INDENTS: When dwSubType is SCCCA_INDENTS, dwData1 can be SCCCA_LEFTINDENT (dwData2 represents the left indent), SCCCA_RIGHTINDENT (dwData3 represents the right indent), SCCCA_FIRSTINDENT (dwData4 represents the first line indent), or any of these values OR-ed together.
SCCCA_OCE: This content type provides information about the original charsets of the characters that follow. dwData1 represents the charset as defined in vtchars.h.
dwData1: Depends on the value of dwSubType.
dwData2: Depends on the value of dwSubType.
dwData3: Depends on the value of dwSubType.
dwData4: Depends on the value of dwSubType.
pDataBuf: Text buffer. Filled with one or more single- or double-byte characters.
dwDataBufSize: Size of pDataBuf, in bytes.
This content type denotes document text, including special characters such as page breaks and tabs.
The technology guarantees that the text generated by the Content Access technology is identical to the text generated by the Outside In Viewer technology raw-text feature. This allows character counts generated at indexing time using Content Access to be directly mapped to viewer positions at viewing time for search-hit highlighting. However, Content Access has abilities beyond the raw-text feature of the Viewer, such as the ability to retrieve non-visible text such as document properties and hidden text, and the ability to retrieve text from embedded documents.
When the output character is DBCS or Unicode, the character count will not be the same as the buffer byte count because these character sets may generate more than one byte per character. The byte ordering used for multi-byte character sets such as these will be system-dependent; on a computer using an Intel processor, the low byte will be first.
It is important to note that generated numeric data fields, such as date, time, and spreadsheet numbers, are not included in the content returned by SCCCA_TEXT. For information on how such text can be returned by Content Access, see "SCCCA_GENERATED: Generated Information".
This section lists the applicable parameters and corresponding values.
dwType: SCCCA_TEXT
dwSubType: One of the following values:
SCCCA_DOCUMENTTEXT: Regular document text is returned with this subtype.
SCCCA_SPECIALTEXT: Used to return text elements that are manufactured by the technology due to special formatting attributes.

SCCCA_ALLCAPS
SCCCA_BOLD
SCCCA_DUNDERLINE
SCCCA_HIDDEN
SCCCA_ITALIC
SCCCA_OUTLINE
SCCCA_REVISIONDELETE: Text that has been deleted from the final version of a document as a result of a revision.
SCCCA_REVISIONADD: Text that has been added to the final version of a document as a result of a revision.
SCCCA_SMALLCAPS
SCCCA_STRIKEOUT
SCCCA_UNDERLINE
SCCCA_UNKNOWNMAP: This flag is set when PDF files don't contain a ToUnicode map. This indicates that the mappings may or may not be correct.
dwData1: Number of characters provided in pDataBuf
dwData2: Original character set of the text in pDataBuf
dwData3: Reserved
dwData4: Reserved
