Hi.  I'm using the REST OSLC API (described at https://jazz.net/wiki/bin/view/Main/ResourceOrientedWorkItemAPIv2) to issue a query of change records, but I only want change records where the parent has an attribute equal to a certain value.  I tried the following, but it doesn't work:

  dc:type="com.ibm.stg.workItemType.changeRecord" and 
  rtc_cm:com.ibm.team.workitem.linktype.parentworkitem.parent{rtc_cm:com.ibm.stg.attribute.environmentFoundIn}="CUST" 
  and dc:created>="2013-04-01T00:00:00.000Z" and dc:created<="2013-04-30T23:59:59.999Z"

Although I can use the brace syntax to request a certain parent attribute as a return property of the query, I don't seem to be able to use that syntax in the query itself to check a parent attribute.  Is there another way to accomplish this?  The web page query interface supports this kind of nested checking, so I'm hoping that the REST API does too.

Thanks.
