An attribute list declares additional properties that further describe an element. An attribute list declaration has the syntax:
<!ATTLIST element_type attribute_values default_value>
For example, a list element has four attributes: type, ordertype, spacing, and continue. Values for each type are declared. The last column shows the default values. Because only one value exists for the continue attribute, a default value is omitted.
<!ATTLIST list type ( order
bullet
plain
check ) bullet
ordertype ( ualpha
lalpha
arabic
uroman
lroman ) arabic
spacing ( tight
loose ) tight
continue (continue) #IMPLIED >
This markup creates a numbered list (uppercase alphabet) that supplies extra spacing between list items.
