IMHO there is nothing to say here, but of course a protocol definition that
uses UTF-8 needs to cover these questions.
Worked example:
objective = [objective-name, objective-flags, loop-count, ?objective-value]
objective-name = text
objective-value = any
loop-count = 0..255
All objectives are identified by a unique name which is a UTF-8
string [RFC3629], to be compared byte by byte.
[draft-ietf-anima-grasp-15 page 37]
It might be worth a note in CDDL to say that CDDL is agnostic on this
but protocol specs need to cover it.
