I'll try to rephrase my questions/remarks, aiming at clarification:

i) Generally speaking: can the RFC-to-be say "MUST be compliant with 
[xxx]" if
- [xxx] says "MUST be compliant with [yyy]" *and*
- [yyy] contradicts the RFC-to-be ?

ii) Will the proposed "EMTA devices implementing this MIB Module MUST be 
compliant with [...] [PKT-SP-PROV]" (hence the relation of this thread 
to #4) introduce a stronger requirement than the existing normative 
reference to [PKT-SP-PROV], REFERENCE'd in some MIB objects? If so, is 
this fully intentional?

If it's only a chicken-and-egg problem, then there'll hopefully be a 
chicken following the egg (or vice versa) at the end. ;-)
