Example
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.

<!-- Define an enumeration of the platform attribute, equal to

<!-- 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:

</subjectScheme>Attributes
The following attributes are available on this element: ID attribute group, @status and @base from Metadata attribute group, @outputclass, Debug attribute group, @class (Not for use by authors), and the attributes defined below.
- @name (REQUIRED)
- Defines an attribute that will take a set of enumerated values.
- @translate
- Indicates whether the content of the element
should be translated or not. For this element the
default value is "no". Setting to "yes" will
override the default. The DITA architectural
specification contains a list of each OASIS DITA
element and its common processing default for the
translate value; because this element uses an
actual default, it will always be treated as
translate="no"unless overridden as described. Available values are:- no
- The content of this element is not translateable.
- yes
- The content of this element is translateable.
- -dita-use-conref-target
- See Using the -dita-use-conref-target value for more information.
