Sorry, but I can't let this one go by without asking:


I completely do not understand the claim of non-"interoperability" here.

Since the record(s) in question are not created with ADSP in mind, then the 
domain owner cannot be said to be participating in ADSP, with respect to this 
check.

SO how is inter-operation hurt or hindered by this specification's making the 
check normative vs. non-normative?
