title: In SOAP MTOM, what is the syntax to specify "content-id" in Attachment Part section?
body: <p>On this <a href="http://axis.apache.org/axis2/java/core/docs/mtom-guide.html#MTOM_Backward_Compatibility_with_SwA" rel="nofollow">http://axis.apache.org/axis2/java/core/docs/mtom-guide.html#MTOM_Backward_Compatibility_with_SwA</a> link, the "content-id" is specified in angular brackets. <br>
  --MIMEBoundary4A7AE55984E7438034 <br>
  content-type: application/octet-stream <br>
  content-transfer-encoding: binary <br>
  <strong>content-id: &lt;1.A91D6D2E3D7AC4D580@apache.org></strong> <br>
  <br>
  In XOP element in SOAP Part, it is referred as - <br>
  &lt; xop:Include <strong>href="cid:1.A91D6D2E3D7AC4D580@apache.org"</strong> 
                          xmlns:xop="http://www.w3.org/2004/08/xop/include" >
  <br>
  <br>(No angular brackets here )
  <br> I don't see anywhere that the angular brackets are mandetory.
  I am using SAAJ APIs and it seems they don't attach any brackets to the content id provided.
  <br>
  Can anyone put some more focus on this ?</p>
