If we say that EARL is a vocabulary defined by different specifications, 
then the EARL vocabulary _does_ change if one of the parts changes.

Another proposal could be to not version EARL the vocabulary, but only 
the parts. Then the schema document would have to be called "EARL Schema 
1.0", as already written in an earlier mail.

The registration of another header to be used in HTTP will not change 
the HTTP-in-RDF schema, but only the http-headers.rdf.

I think that's a sligtly different thing.
