Shouldn't we have 2 sets of capabilities? Svn and protocol specific?

Do we want to use filtering? Say a 1.6 client has svndiffN and sends it to a
1.5 server, then thee 1.5 server won't filter it out and pass it to the
start-commit script.

Unless I'm misunderstanding something how the new capabilities work.
