Hi Rimas:
The WG considered your LC comment and has chosen to clarify that the message property
"[destination]: IRI (mandatory)" will be replaced by 
"[destination]: IRI (1..1)" where (x..y) is short for minOccur=x and minOccur=y.

In other words, there is only one [destination] property associated with a message.

At the same time, the WG has also decided to make the same change to
"[action]: IRI (mandatory)" replacing it with
"[action]: IRI (1..1)".

Please let the WG know if this does not address your concern - within two weeks, please,
Thanks,
Nilo
(on behalf of the WS-A WG)
