Subject: Action 032304-2 proposal

Title: Action 032304-2 proposal

Action 032304-2 proposal (from Sunil / Jacques)

- Issue 1: RetryMaxTimes and RetryTimeInterval are really meaningful only
for Callback reply pattern. The spec is silent on this limitation.
For Poll reply patttern, the resending effort can be associated with the polling:
The spec is silent on the resending policy in that case.

- Issue 2: RetryMaxTimes and RetryTimeInterval have a precise interpretation, that actually
is just one way to do the resending effort. Other ways should not be excluded.

- Issue 3: there is no indication of how often a Poll request will be sent.
Yet this should be controlled by the RMP (and remain transparent to the application).
A parameter to control this (time period, or number of messages, or both) need be defined.

Proposal Outline:

1- RM Agreement items can be either Required / optional :

Update section 1 to reflect that:

- some RM Agrement Items are "required" by this specification:
an implementation must be able to represent them and their value.
They are critical to the specified reliability mechanisms:
GuaranteedDelivery, NoDuplicateDelivery, OrderedDelivery, GroupMaxIdleDuration
GroupExpiryTime, ExpiryTime, ReplyPattern

- Some RM Agrement Items are "optional" for this specification:
Two communicating parties do not have to both agree on using them.
An implementation may represent them and use them to locally control the execution
of reliability features:
RetryMaxTimes, RetryTimeInterval, PollFrequency

2- Introduce PollFrequency optional agreement item, as a way to control the frequency of polling.

3- update Section 3.1 (guaranteed delivery) to stress the optionality of
agreement items that control resending, and cover all reply patterns.
E.g. For each poll, after looking at the Poll response, the RMP will resend all messages
that have not been acknowledged or faulted. Poll frequency is also controlled.

4- Mention that some agreement items are set by business partners, some
are intended to be set more dynamically, depending on network conditions, messaging
