I think I'll let it "age" a little while to allow others to comment. If no other comments come in, then we can go ahead. If this moves along fast enough I have a good use for it in the in-progress 4566bis (SDP). There may be one thing to be slightly concerned about: ABNF validators. Without updating them validation of ABNF that uses this will fail.
