Daniel,
	I am embarrassed to say that you are absolutely right.  I was  
convinced that this property was in OWL-S; but looking (briefly) at the  
previous versions, I can't find it.

This does raise some interesting questions:

1) profile:has_process
This is a functional property, pointing to a "Process".  Should this be  
functional, or may we want a profile to point to several processes (and  
what would this mean)?

2) inferring the profile given the process
If we have a full OWL-S model in some RDF store or reasoner, is it  
possible to identify the profile given a reference to the process  
model?  Because of the "has_process" property, we can go the other way  
round (and yes, this means we can do tricks with RDQL), but, for  
example, could we generate the class of all profiles for a given set of  
processes?  This would be necessary if, for example, we wanted to know  
the different non-functional parameters (attached to the profile) that  
related to a given composition of processes?
