This'll need a test case, in any case.
Adrian/Paul: Pondering this, any thoughts on how conflicts in the vendor
extension range of attributes, forms, etc, should be resolved if they ever
come up? (each vendor is free to define them as they wish, so it could be
that multiple vendors have different definitions of the same code/number &
would be ambiguous) I don't see any reason to block this patch if it
doesn't have such a conflict, since there are already other vendor
extension codes supported here for a variety of vendors - but does make me
