Thanks for the comments ; they come at the right time as we are
currently working on what will become the v6 of this draft. The
precision about the use of normative sections in particular is
welcome.

Although other work keeps getting in the way I hope to post v6
sometime this week. We are also thinking of updating our current
implementation of an older protocol version to provide a working
proof-of-concept, although this will likely take some more time to be
done.

Cheers,
Alex.
