# `%*.class;` Parameter Entities

`%*.class;` Parameter Entities — Parameter entities which define the DocBook classes

## Synopsis

Classes group elements of a similar type, for example all the lists are in the `%list.class;`

If you want to add a new kind of something (a new kind of list or a new kind of verbatim environment, for example), you generally want to add the name of the new element to the appropriate class.
