UML Standard Profile
tag definition applicableSubset
This tag definition, which only applies to profile packages, lists the metaelements that are used by the associated profile. The value associated with this tag definition is a set of strings, where each string represents the name of an applicable metaelement. Note that the use of applicable subset does not necessarily exclude the use of any metaelements, but clearly identifies which ones are referenced from the associated profile. Further note that the tag definition applies only to the immediately associated profile. If a profile combines several other profiles using import or generalizations, the applicable subset only applies to the immediately associated profile. The absence of an applicable subset tag definition means that the whole UML metamodel is applicable.
