Hi,
I am commenting in lieu of Monica Martin and Pete Wenzel. They had
reviewed the LC edition [1] of the MTOM Serialization Policy Assertion
1.1 document. The same issue is present in the latest editor's working
draft [2].
The text in paragraph 3.2 is garbled. Here is how it looks like now:
/wsoma:MTOM/@wsp:Optional="true"
Per Web Services Policy [WS-Policy]
<http://www.w3.org/2000/xp/Group/2/06/LC/mtompolicy.html#WS-Policy>,
this is compact notation for two policy alternatives, one with and
one without the assertion. This indicates that the behavior
indicated by the assertion is optional, specifically that
non-MTOM-encoded exchanges are also supported by the endpoint.
When an endpoint reflects a compact policy expression with the MTOM
assertion marked with |wsp:Optional='true'|, it may be difficult to
know which alternative has been engaged. In such cases, if a request
message is received that is an |application/soap+xml| message, then
the receiving endpoint SHOULD respond (if at all) with an
|application/soap+xml| response message unless there is some other
indicator that specifies that the response is to be sent using MTOM
encoding.
ensure that a response message is serialized as
|application/xop+xml| a client can send an |application/xop+xml|
request message.
For example, when using SOAP/HTTP binding, the |Accept| HTTP header
value of |multipart/related; type=application/xop+xml| in the
request message indicates that the response may be sent using MTOM
encoding.
We assume that it was intended to say instead:
/wsoma:MTOM/@wsp:Optional="true"
Per Web Services Policy [WS-Policy]
<http://www.w3.org/2000/xp/Group/2/06/LC/mtompolicy.html#WS-Policy>,
this is compact notation for two policy alternatives, one with and
one without the assertion. This indicates that the behavior
indicated by the assertion is optional, specifically that
non-MTOM-encoded exchanges are also supported by the endpoint.
When an endpoint reflects a compact policy expression with the MTOM

the receiving endpoint SHOULD respond (if at all) with an
|application/soap+xml| response message unless there is some other

encoding.
For example, when using SOAP/HTTP binding, the |Accept| HTTP header
value of |multipart/related; type=application/xop+xml| in the
request message indicates that the response may be sent using MTOM
encoding.
In the absence of such an indicator, a client can ensure that a
response message is serialized as |application/xop+xml| by sending
an |application/xop+xml| request message.
