Thanks guys for the replys. I discovered that I needed this capability when the toolbox VI that I use to make hidden front panel controls appear didn't work on items within a cluster and no matter how hard I looked at the property node off the array of generic front panel references, I couldn't find a "cluster contents" reference.
It occured to me shortly after I had asked the question to cast the generic reference to a cluster-specific reference and when I did that then I could find the references to the controls within the cluster.
FWIW, I've attached the aforementioned toolbox VI (lv 7.1.1) for which I needed this.
