Hi Bruno, John Scudder was kind enough to provide extensive argumentation offlist on why something along these lines should be done. We'll work on a proposal. The length indicator is a neat idea, thanks for sharing.

What if someone needs to advertise additional info to an existing cease subcode? cf Jeff's email regarding the pain of changing subcodes. So let's forget about the TLV. What about just adding the length of the string? This would still allow adding fields after the string, while having a negligible/null cost?
