[ebxml-dev] CPA example

[Keith Babo <keith.babo@sun.com>]

I have a quick question on the structure of the 
draft-cpa-example-015.xml document (which I grabbed from the ebxml-cpa 
archive list).  It appears as though "Purchase Order Request Action" is 
defined twice under CanSend elements; once for a synchronous delivery 
channel, and once for an asynchronous delivery channel.  Is this right?? 
 My understanding was that a given action could only appear once within 
a CanSend element under a given Party.

The 1.09 spec has this to say on the matter (pg. 34, line 1316) :

Under a given PartyInfo element and among all subordinate CanSend 
elements, there SHALL be only one ThisPartyActionBinding element whose 
action attribute has a given value.

Is this an error in the example CPA, or am I just missing something? 
 The following is excerpted from the example CPA document :
