Subject: [MMUSIC] ABNF syntax in 3388bis

I have a question about http://www.ietf.org/id/draft-ietf-mmusic-rfc3388bis-03.txt

Section 5 of -03 version says:

           group-attribute     = "a=group:" semantics
                                 *(space identification-tag)
           semantics           = "LS" / "FID" / semantics-extension
           semantics-extension = token

I don't know every detail of the ABNF syntax, but here the identification tags seem to be totally optional, whereas we at least need two of them to be able to use the 'group' attribute, right?

So, should not we rather have:

           group-attribute     = "a=group:" semantics
                                 2*(space identification-tag)
           semantics           = "LS" / "FID" / semantics-extension
           semantics-extension = token
