Getting Changes from Changeset

Hello,

I am using the following query to retrieve the Changeset.

OSCL Query:
https://serverName:9443/ccm/resource/itemOid/com.ibm.team.scm.ChangeSet/_HFxrmiEbEeS7m-qENunxUw?_mediaType=text/xml

Getting the following response:

<scm:ChangeSet itemId="_HFxrmiEbEeS7m-qENunxUw"
	properties="">
	<stateId>_W8aNECEbEeS7m-qENunxUw</stateId>
	<immutable>true</immutable>
	<contextId>_Dp6kMdwTEd2jUupDpQV1Rw</contextId>

	<changes>

		<kind>2</kind>
		<before>_nDuHQBhzEeS88s3Rov8pNA</before>
		<after>_HUNJJSEbEeS7m-qENunxUw</after>
		<item itemId="_k5S2oBhzEeSht4FX-gq3Zg" xsi:type="filesystem:FileItemHandle" />
	</changes>
	<component itemId="_RvxoEBhzEeS88s3Rov8pNA" />
	<owner itemId="_FAv8gA4GEeSsZdvBzERdWQ" />
	<xComponentLink xsi:nil="true" />
</scm:ChangeSet>

I would like to get the Changes detail. It would be great if someone shares the OSLC 
query to retrieve Changes details.

Thanks,
