On \cat being a publishable, vernacular "character style"

[davidg-sil]

I feel that there should be some other class name for \cat ... \cat* e.g. special or control, rather than its current designation.
The description in the specification that it is a <TAG> is correct in itself, but the stylesheet declaring it to be a character style with properties 'publishable' 'vernacular' 'note' might give someone the impression that it is supposed to appear in the output.

For the record, PTXprint is also allowing styling to be applied by \cat ... \cat*, and has also extended its application to categorize various other markers beyond side-bars and extended notes:

• All classes of notes (because not doing so would add complexity!)
• tables (put just after the first row, e.g. \tr\cat genealogy\cat*)
• paragraphs (e.g \ip\cat important\cat*).
