I didn't mean to suggest that the Xerox tools are perfect, but rather
that someone who has a working parser is very unlikely to need to
change anything to make them work for cgi. Certainly one can improve
notation, and of course not everyone has the same ideas as to what
sorts of rules and representations they prefer, so there is room
for variation.
