NEW ISSUE: Definition for "Reliable Message"

Title: Definition for "Reliable Message"

Description: there are several references to "reliable message" (section 1, 2 intro, 2.1, 2.3) that are not backed by a clear definition.

Justification: Terminology section is defining key concepts, yet does not explain what a reliable message is (and now other definitions are also referencing "reliable message"). The main requirement of inclusion of a wsrm:Sequence element which could back an intuitive definition, is not currently related to this expression at all, (related to DA instead) which is confusing.

Target: core

Type: editorial

Proposal:

1- Add a terminology entry. It could be:

Reliable message: a message submitted by the Application Source to an RM Source via the "Send" operation,

for transmission over the protocol defined in this specification.

2- In 3.1: associate the main protocol requirement (Sequence element) with the definition of "reliable message" instead of with a vague requirement of being subject to some DA:

Replace:

"Messages for which the delivery assurance applies MUST contain a <wsrm:Sequence> header block."

With:

"Reliable Messages MUST contain a <wsrm:Sequence> header block."

(DA and protocol being in fact separately defined, DA should now more abstractly mandate the use of "reliable messages" if we still want to pre-req one to the other.)
