I know - I intend to give a comment on 4566bis, saying that I think the syntax shall be in ABNF form. The only place 4566bis currently suggest to put the ABNF is in the IANA registration, but I'd rather see it in the attribute definition.

Ok. So, based on the suggestion in that thread, the ABNF would be:

           attribute               =/ bundle-only-attribute

           bundle-only-attribute   = %s"bundle-only"

....right?
