Profiles are applied to the element the cursor is in. Refer to
Applying profiles for detailed steps on applying profiles.
Individual profiles are categorized in classes. Classes may contain standard and unique profiles. Classes may also be categorized with other classes.
Depending on the document type's profiling configuration, preset collections of selected individual profiles may be available as profile groups. Applying or setting a profile group is the same as applying or setting each of the individual profiles within the group.
