[skraza]: On the flip side, can this still not cause confusion if an
author 
of a future (mode-bound) application misses this (default)
statement/requirement;
and thinks/assumes (just based on RFC 5036) that its new application will
use the negotiated mode, whereas, in reality, the negotiated mode won't
apply 
unless stated explicitly.

For this revision of draft, I will take the comment (use of "MUST") from
other authors, 
and keep your suggestion open for WG discussion/consensus/closure in
subsequent Revs.

Rgds,
