Ah, ok. I think there is another issue. We have two grammars and two
parsers, one for the OpenLDAP style schema files and one for the the
syntax checkers. Some of these relaxions are already present in the one,
some in the other grammar. Perhaps we should try to could combine both
into one grammar?
