+1, with the following two changes.

1) RELAY ATTRIBUTE
------------------

Add support for the SOAP 1.2 @relay attribute:

<*dataEntry* ...
              relay= "xs:Boolean"?
              ...
</*dataEntry*>

2) EDITORIAL CHANGE
-------------------

Change "intermediary" to "node" in the following sentence, as the role 
may be set manually to ".../ultimateReceiver":

"to identify a particular intermediary along a message path"
