No.

It's a bit roundabout, but the information is there.

As you probably know, in OWL-S composition focuses on processes, not 
services.  So your composition will be centered about a process PC 
(let's say), which is composed of processes PX and PY.  For each process 
there can be a property called "describes" that refers to the 
corresponding service instance.  Then, by visiting each service instance 
you can follow the "presents" property to find the associated profile 
instance (or instances).
