 Yes, the single-quote form is no longer promoted. The Matrix, however, had
'null_coord_rel and 'implicit_coord_rel until 07 May 2014, so any Matrix
grammars customized prior to that date would have them (although they might
not be in use). For that reason I support them, but I didn't mean to
legitimize their use. I've updated the PredicateRfc wiki page to make that
more clear.

quantifiers are treated specially in the MRS Lisp code and that actually

Ok, this is good to know. I have some more questions, but I'll start a new
thread since it strays from the topic of this thread.
