"No XOP Parts"

Due to a bug in Axis2 1.3, when we call a web service from a .NET application using WSE 3.0 and MTOM, we receive this error: "WSE1608: No XOP parts were located in the stream for the specified content-id: ...".

The problem is that in Axis2 response we receive something like this:

The problem is with start attribute, that doesn't match with the content-id of the object root, because it hasn't < and >. According to RFC 2387: "The 'start' parameter, if given, points, via a content-ID, to the
body part that contains the object root.".
A example from this RFC:

Content-Type: Multipart/Related; boundary=example-1
start="<950120.aaCC@XIson.com>";
type="Application/X-FixedRecord"
start-info="-o ps"

Content-Type: Application/X-FixedRecord
Content-ID: <950120.aaCC@XIson.com>

Here is a link to this issue from Axis2:
https://issues.apache.org/jira/browse/AXIS2-3196.
Here is a link to the culprit version change: http://svn.apache.org/viewvc?view=rev&revision=555276.
Here is a link to the correct version change: http://svn.apache.org/viewvc?view=rev&revision=573037.

Here is the .NET call, that is correct according to RFC:
