By "parameter syntax" I mean the syntax of the Authentication HTTP header.

Is all this only around the scope parameter? My mail cited below is with
regards to the character set for a valid scope parameter, which we should be
able to define and then lean on the HTTPbis spec for the actual parameter
syntax.

I did already back the statement that this is the working group consensus with
the e-mails attached in this note sent to you on December 12, 2011:
- http://www.ietf.org/mail-archive/web/oauth/current/msg08042.html
But since that apparently wasn't convincing to you that this working group
decision represents more than "just me disagreeing with you", here are
references to individual messages referenced in the above e-mail:
- Eran Hammer-Lahav:
http://www.ietf.org/mail-archive/web/oauth/current/msg07698.html
- John Bradley:
http://www.ietf.org/mail-archive/web/oauth/current/msg07699.html
- William Mills:
http://www.ietf.org/mail-archive/web/oauth/current/msg07700.html
- Mike Jones:
http://www.ietf.org/mail-archive/web/oauth/current/msg07701.html
- Phil Hunt: http://www.ietf.org/mail-archive/web/oauth/current/msg07702.html
- Justin Richer:
http://www.ietf.org/mail-archive/web/oauth/current/msg07692.html
As for your assertion that the specs are in conflict, yes, the Bearer spec
includes a different decision than a RECOMMENDED clause in the HTTPbis spec
(which was added after the Bearer text was already in place). However, it is
not violating any MUST clauses in the HTTPbis spec. Given that no MUSTS are
violated, I don't see it mandatory for this tension to be resolved in favor of
one spec or the other in order for both to be approved as RFCs. I look forward
to seeing that happen soon in both cases (and for the OAuth core spec as well).
Best wishes,
-- Mike

It would be helpful if you could back this statement with pointers to mails. As
far as I can tell it's just you disagreeing with me.
Back to the facts:
a) the bearer spec defines an HTTP authentication scheme, and normatively
refers to HTTPbis Part7 for that
b) HTTPbis recommends new scheme definitions not to have their own ABNF, as the
header field syntax is defined by HTTPbis, not the individual scheme
c) the bearer spec defines it's own ABNF nevertheless
So the two specs are in conflict, and we should resolve the conflict one way or
the other.
If you disagree with the recommendation in HTTPbis, then you really really
should
come over to HTTPbis WG and argue your point of view.
If you agree with it, but think that the bearer spec can't follow the
recommendation, then it would be good to explain the reasoning (optimally in
the spec).
If you agree with it, and think the bearer spec *could* follow it, then...
change it, by all means.
Anyway, if this issue isn't resolved before IETF LC then it will be raised
again at that time.
