and let's be fair here: does Corvey really add more to the WH List than eg the Pyu cities or Shahr-e-Sokhta
I agree entirely - and Corvey is another of my "ticks" this year too - but to quote from my review of last year "But does the list really need yet another example of Carolingian Architecture? It already has Aachen, Lorsch, Mustair and Reichenau. That is not to gainsay the historic significance of the Westwork but not everything which is "important" should become "Welterbe"."
I haven't yet heard the WHC discussion on the site - ICOMOS supported the OUV and wanted "referral" on technical matters. An example of getting it "wrong" in both direction I feel!
I have never yet heard a WHC object to the AB recommendation that OUV is present -only in the opposite direction!
It was indeed good to have the "expert" from Cambridge speaking to assist Myanmar on the OUV of Pyu cities amd really "overwhelming" ICOMOS's "anonymous" experts whoever they were. Also good that she was from UK so the concern that ICOMOS doesn't use "experts" belonging to the nominating culture was demonstrated to not be an absolute necessity!
