The <attributedef> element specifies the attribute to which a set of controlled values from a subject scheme map are to be applied.

subjectScheme | ( (data or data-about) (any number) ) |
In this example, enumerations are specified for the platform and otherprops attributes. Note that the enumeration identifies a category of values; the values within the category are valid, while the category itself is not a valid value. For example, in the code sample here, the platform attribute is associated with the enumeration for the category "os"; all values within the "os" category are thus valid on the platform attribute, while the value "os" itself is not.
<subjectScheme> <!-- Pull in a scheme that defines unix OS values --> <schemeref href="unixOS.ditamap"/> <!-- Define new OS values that are merged with those in the unixOS scheme --> <subjectdef keys="os"> <subjectdef keys="linux"/> <subjectdef keys="mswin"/> <subjectdef keys="zos"/> </subjectdef> <!-- Define application values --> <subjectdef keys="app" navtitle="Applications"> <subjectdef keys="apacheserv" href="subject/apache.dita"/> <subjectdef keys="mysql" href="subject/sql.dita"/> </subjectdef> <!-- Define an enumeration of the platform attribute, equal to each value in the OS subject. This makes the following values valid for the platform attribute: linux, mswin, zos --> <enumerationdef> <attributedef name="platform"/> <subjectdef keyref="os"/> </enumerationdef> <!-- Define an enumeration of the otherprops attribute, equal to each value in the application subjects. This makes the following values valid for the otherprops attribute: apacheserv, mysql --> <enumerationdef> <attributedef name="otherprops"/> <subjectdef keyref="app"/> </enumerationdef> </subjectScheme>
Name | Description | Data Type | Default Value | Required? |
---|---|---|---|---|
name | Defines an attribute that will take a set of enumerated values. | 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 |
