Hmm. That seems questionable to me. It means that there will be an 
important requirement on ACR that is specified independently of the main 
body of specification of ACR requirements.

I would think it clearer if there is a requirement for calling party 
category as a general mechanism, and then, if ACR is expected to behave 
differently in the presence of calling party category, that should be 
called out as an ACR requirement.

I think it is merely a matter getting the references done correctly. 
Perhaps this particular requirement can't be finalized until the REQ-CAT 
is finalized.
