For the discussion:

and following.

* Trevor Perrin provided a quick briefing about the current status 
of the work and refered to some of the open topics (options 
representation, base-64 encoding for transferred documents, 
enveloping/enveloped transforms).

* Juan Carlos Cruellas expanded on the issues covered in his message:
http://www.oasis-open.org/archives/dss/200310/msg00018.html
and requested that the ambiguities be resolved.

NEW ACTION 24: Trevor Perrin to produce a table for all situations 
involving enveloping/enveloped signature client transforms and 
submit it to the mailing list.

* Juan Carlos Cruellas suggested that the <KeySelector> element 
be directly replaced with a <ds:KeyInfo> element.  He also proposed 
that named types be defined.  Trevor Perrin said that the current 
approach taken by Rich Salz and himself produces shorter schemas.

* Juan Carlos Cruellas asked whether the <requestID> element could be 
an optional attribute instead; also, whether representing tranferred
documents as base-64 blobs is appropriate in the character-based 
XML universe.

6. Scope of the DSS TC in the light of ABA activities.

Ref. message:
http://www.oasis-open.org/archives/dss/200309/msg00109.html

* Trevor Perrin thought the ABA approach wouldn't affect the core 
protocol, and could be supported in an extension profile of DSS.
Juan Carlos Cruellas noted that the ABA approach breaks XMLDsig
in terms of the semantics and processes assumed for the <ds:Signature> 
element.  Trevor Perrin and Hal Lockhart agreed that the ABA 
approach follows the XMLDSig format but abuses the semantics 
associated with <ds:Signature>.  There was consensus to keep 
the issue alive and request that John Messing present his thoughts 
to the mailing list.

7. Short term plans elaboration. This could include:

- Deadline estimation for the consolidation of the first version
of the Sign Request part of the protocol document.

- Starting date on Sign Response part of the protocol document.

* There was consensus to continue discussion in the mailing list 
of the issues related to <SignRequest> and <SignResponse> for 
the next two weeks, with the goal to have a mature version ready
in one month's time.  Trevor Perrin thought work could proceed 
in parallel on the <VerificationRequest> and <VerificationResponse>.

* Tim Moses asked that the timestamp schema be included in the document.

8. Any other business

* none

9. Close

* Juan Carlos Cruellas adjourned the meeting at 12:53pm Eastern time.

* Done.

ACTION 23: Nick Pope to start a discussion of alternatives for handling
implicit paramaters.
