I'd include the regexp.  You might call the attribute "match".  That would
fit right in with the notion of 'productions'.  Only problem is, escaping
"<" and so on would make them harder to read.  If the need to escape
characters makes the regex's too unpleasant, follow the approaches taken in
RELAX.  After all, RELAX specifies grammars too.
