Re: Issue: How CPA is used in the spec

[Rich Salz <rsalz@zolera.com>]

Okay, here is text that hopefully addresses the comments of David's
Fischer and Burdett:

The values for the reliable messaging parameters are determined by
appropriate elements from the CPA as identified by the optional CPAid
element. If a receiver determines that a message is in conflict with the
specified CPA, the appropriate handling of this conflict is undefined by
this specification. (For example, it may ignore the conflicting
parameters, or accept some or all of them.) Therefore, senders SHOULD
NOT generate such messages unless they have prior knowledge about the
receiver's capability to deal with this conflict.

If a receiver chooses to generate an error as a result of a detected
inconsistency, then it MUST report it with an errorCode of Inconsistent
and a severity of Error. If it chooses to generate an error because the
CPAid is not recognized, then it MUST report it with an error code of
NotRecognized and a severity of Error.
