Something like that, yes.

Yes, although that doesn't mean that users can modify the special-use
attributes themselves, unless some sort of web management interface has
a dialog for that. The METADATA/CREATE-SPECIAL-USE capabilities would
provide a standard means for a user to do this, from within the MUA.
