    Title: persistDuration
    

    



    Jacques,
    

     
    

    David may be taking today off.  I'll jump in with an 
attempt at an answer.
    

     
    

    The MessageId value is required to be unique.  We mean 
globally, universally and forevermore unique.  Based on that requirement, a 
duplicate message should never be created except as part of retries for 
reliable messaging (or through a faulty transfer).  MSH 
implementations are not required to remove messages from their persistent store 
immediately after their duration has expired, leading to other problems with 
identifier reuse.
    

     
    

    The wording you've called out basically says the same thing as 
our equation relating retries and time to live plus "don't waste time and energy 
sending something after its time to live has expired".  I'd recommend 
including words to that effect in the description of sending MSH reliable 
messaging behaviour.
    

     
    

    thanx,
