I want to list changeset and related parts with oslc by using xml. First I list workitem (https://server:9443/jazz/oslc/workitems/1112.xml) , and then focus oslc_cm:collref (https://server:9443/jazz/oslc/workitems/1112/rtc_cm:com.ibm.team.filesystem.workitems.change_set.com.ibm.team.scm.ChangeSet).For this example, it lists 4 parts.
At the end, I write https://server:9443/jazz/resource/itemOid/com.ibm.team.scm.ChangeSet/_P6rykd3TEd-mz4Y8Qcp1YQ?_mediaType=text/xml
It shows like
- <changes>
<internalId>_QGTMsN3TEd-mz4Y8Qcp1YQ</internalId>
<kind>2</kind>
<before>_2o-6LtzoEd-mz4Y8Qcp1YQ</before>
<after>_QB-th93TEd-mz4Y8Qcp1YQ</after>
<item>
</changes> ...

How can I list related parts(changed-modified parts) of changeset with it?
