Re: Fw: [ws-rx] Issue 129: Define "discard"

Logically if a transaction rolls back then the message is not 
"processed", because any processing is undone. In fact worrying about 
the difference between not processing it and rolling it back is 
definitely "getting into implementation details".

So here is what I would propose - (slighty reworded again).
In the following definitions of allowable values, the term 'discard'
indicates that a particular message is not processed by the Application 
Destination.

My problem with the other text is that I don't think its clear. I have 
to say I have some sympathy with the view Jacques expressed: that this 
is the one and only point in the text where the word deliver is applicable.
