NEW ISSUE: How does a RM Destination reject an offered Sequence?

[Matthew Lovett <MLOVETT@uk.ibm.com>]

Title: How does a RM Destination reject
an offered Sequence?

Description:
Section 3.1 lines 254 - 256 in wsrm-1.1-spec-wd-06.pdf says:
<wsrm:CreateSequence> MAY carry
an offer to
create an inbound sequence which is
either accepted or rejected in the
<wsrm:CreateSequenceResponse>.

However, there is no way to reject the
offered sequence without faulting the entire CreateSequence message, as
lines 348 - 352 also say:
/wsrm:CreateSequenceResponse/wsrm:Accept
This element, if present, enables an
RM Destination to accept the offer of a corresponding Sequence for
the reliable exchange of messages transmitted
from RM Destination to RM Source. This element MUST
be present if the corresponding <wsrm:CreateSequence>
message contained an <wsrm:Offer>
element.

I believe this is inconsistent. We should
either define how a RM Destination can accept an inbound Sequence while
rejecting the offer, or adjust the text in lines 254 - 256 to say that
it is not possible.

Justification: The specification should be consistent.

Target: core

Type: design

Proposal:
As noted above, I can see 2 alternatives. I believe the way to go is to
say that it is not possible to reject an offered Sequence without rejecting
the entire CreateSequence message.

Reword lines 254 - 256 to read:
<wsrm:CreateSequence> MAY carry
an offer to
create an inbound sequence which is
then accepted in the
<wsrm:CreateSequenceResponse>.
If the RM Destination is unable to accept the offered Sequence then it
MUST respond with a CreateSequenceRefused fault.

Related issues: none
