Yes, they are, but...

...those identifiers are static variables in the dissectors.

One *could* export them, but that would require code changes, so you
might as well just put a look-up-by-name feature into "epan/proto.c", so
that you don't have to modify dissectors in order to let other modules
get at fields they've registered.
