From section 3.2.1: “this version of the specification does not make use at all of the WSAddressing Endpoint Reference 
data structure” I don’t necessarily have an issue with that decision. I just would like to have a better understanding
 of why it isn’t used. For instance, what made WSA EPR unsuitable for this specification? Also, given that the name 
used is “Data Endpoint Reference (DEPR)” and in fact the data structure looks superficially similar to the WS‐
Addressing EPR (figure under 4.2.1.2.1), this seems sure to cause confusion.
