Andy and Paul seem to see this as an easy thing to include that would have pragmatic benefits while Steve is worried about not being able to define what a property function is and not being able to defend it as in-scope. Have I got that basically right? Is there any sort of compromise to reach here?

Paul & Andy,

Steve & I -- at least -- are concerned that there is no useful way to 
include service description vocabulary for property functions without 
defining what a property function is. And I think we all agree that the 
task of defining what a property function is is out of scope for the 
group at this time.

Speaking for myself, I'm concerned that any text we may come up with 
will need to be pretty vague, and as such will not be at all testable / 
will not really help with interoperability. Interoperable 
implementations will require knowledge outside the spec -- it will 
require people to know (intrinsically?) what a property function is. 
That doesn't sound like a healthy spec. to me.

I'd suggest that the best way forward is for a proponent of including 
this to suggest spec. text - with concrete text, perhaps Steve and I can 
better explain our concerns and/or withdraw our concerns if the text 
assuages our worries. Would someone be willing to do this?
