WCF uses a URL Encoded href cid for xopInclude. However, the Content-Id for the attachment is not URL Encoded. As such, JBossWS is unable to find the attachment.

Example:

<xop:Include href="cid:http%3A%2F%2Ftempuri.org%2F1%2F633631227250468750" xmlns:xop="http://www.w3.org/2004/08/xop/include"/>

--uuid:357c6d9d-d6cf-42e3-bca5-75c8f3761934+id=1
Content-ID: <http://tempuri.org/1/633631227250468750>

Since this is an interoperability issue, I don't know how to create a test case under the test suite to simulate this error.
