Sounds like a reasonable compromise, as making the grammar a superset of all proprietary grammars is also on the ambitious side (done this before, it was horribly arcane and fragile... twitch-twitch). Just thinking out loud here... maybe some form of pass-through quoting would be an elegant way to solve the problem?
