First, many thanks for the huge practical work. I've not studied it in
depth, yet, but I invite people to read it and express opinions about
what we should integrate in -02.

Second, a few details (more substantive comments will follow):

XXX-wsp is already used as a production name in RFCs. See RFC 4234
which have set the example.

Hmmm, I thought the purpose of "core" (appendix B) was precisely to
avoid redefinition. So, it seems to me there is no need to add these
definitions. (See option -t of abnfgen.)
