elementdef

Darwin Information Typing Architecture (DITA) Version 1.2

The <elementdef> element identifies an element on which an attribute is enumerated. When the <elementdef> is left out of an <enumerationdef> element, the enumeration is bound to the attribute in all elements.

Example

In this example, the <lomDifficulty> element has been specialized from the <data> element. The value attribute on the <lomDifficulty> element (but not the value attribute on other elements) is bound to a specific set of values. This means that processors should limit that attribute on that element to the values veryEasy, easy, medium, difficult, or veryDifficult.

<subjectScheme>
  <subjectdef keys="difficulty">
    <subjectdef keys="veryEasy"/>
    <subjectdef keys="easy"/>
    <subjectdef keys="medium"/>
    <subjectdef keys="difficult"/>
    <subjectdef keys="veryDifficult"/>
  </subjectdef>
  ...
  <enumerationdef>
    <elementdef name="lomDifficulty"/>
    <attributedef name="value"/>
    <subjectdef keyref="difficulty"/>
  </enumerationdef>
</subjectScheme>

Attributes

Name Description Data Type Default Value Required?
name Defines the element for which an attribute enumeration is defined. CDATA #REQUIRED Yes
id-atts attribute group (id, conref, conrefend, conaction, conkeyref) A set of related attributes, described in id-atts attribute group      
status The modification status of the current element. new | changed | deleted | unchanged | -dita-use-​conref-​target #IMPLIED No
translate Indicates whether the content of the element should be translated or not. The DITA architectural specification contains a list of each OASIS DITA element and its common processing default for the translate value. yes | no | -dita-use-​conref-​target #IMPLIED No
base A generic attribute that has no specific purpose. It is intended to act as a base for specialized attributes that have a simple value syntax like the conditional processing attributes (one or more alphanumeric values separated by whitespace), but is not itself a filtering or flagging attribute. The attribute takes a space-delimited set of values. However, when acting as a container for generalized attributes, the content model will be more complex; see Attribute generalization for more details. CDATA #IMPLIED No
global-atts attribute group (xtrf, xtrc) A set of related attributes, described in global-atts attribute group      
class, outputclass Common attributes described in Other common DITA attributes
