If by "bridge the header/attribute" you mean adjust keys/values to match
the old version, I don't have a list identifying what changed. This particular
change was caught on chance because of a unit test.
I'm open to suggestions, but the only option I see that has doesn't break
backward compatiblity is isolate the processors back into separate NARs.
