I do not believe this last statement is correct. It seems that an IPCC 
should (must?) have one and only one node-wide unique CCID. Having a 
many-to-one mapping leads to problems. For example, there is a one-to-one 
correspondence between MessageID fields and CCIDs (See section 2, paragraph 5).

I believe there is a flaw in this interpretation. If the CCID is reassigned 
then the old CCID would no longer be valid. In the case described, the old 
Interface ID for the data link has been changed so an in-band CCID using 
the old value would be invalid, since it would no longer match the TE-link ID.

Sincerely,
