I have run following REST command for information on changeset , which gives me output, but don’t seem to find any information related to associated work items. 

https://URL/resource/itemOid/com.ibm.team.scm.ChangeSet/_DdLh0W4KEeSWhvg1spxB0A?_mediaType=text/xml

Output is:

<scm:ChangeSet itemId="_DdLh0W4KEeSWhvg1spxB0A" properties="">
