NEW ISSUE - No indication of how to process NACKs in normal case

Title: NEW ISSUE - No indication of how to process NACKs in normal case

All, 

Here's a description of the new issue I wanted to raise from the discussion of the related issue i005 [1].  

Title: Processing model of NACKs 

Description: Although it is assumed that a NACK will trigger retransmission of a given message from the source to the destination there is no wording in the current version of the spec that describes this feature adequately.

Justification: This will clarify to implementers the spriit of the spec by spelling out in more concrete terms what is currently only implied.

Target: Core

Type: Design

Proposal:

Add the following to the spec directly before the text that is incorporated as a resolution to i005:

Upon the receipt of a Nack, an RM Source SHOULD retransmit the message identified by the Nack as soon as possible. 

Cheers,

Steve
