###### 3.1.3.1.5 category

The <category> element represents any category by which a topic might be classified for retrieval or navigation. For example, the categories could be used to group topics in a generated navigation bar. Topics can belong to multiple categories.

Such classifications are likely to come from an enumerated or hierarchical set.
