   Actually, it is worse than this; the grammar does not permit more than
one of "max-width", "max-height", etc. Also, the use of <param-val> (aka
<byte-string>) as the values of things like max-width precludes the use of
any delimiter, since param-val can contain anything except NUL, CR, and LF.
Things like max-width really should be a positive integer, so the grammar
will need to be tightened down. I'm guessing that what the author was
shooting for was ';' delimited, with positive integer values for everything
but depend=.

   Also, I would expect that stuff like pt=*,96,8,* is not permitted, but
the current grammar permits it.

Best regards,
