LDML Keyboard Descriptions and Normalisation

I'm getting conflicting indications about how the LDML keyboard
description handles issues of canonical equivalence. I have one
simple question which some people may be able to answer.

Is the keyboard specification intended to distinguish between
keyboards that generally output:

(a) NFC text;
(b) NFD text; or
(c) Deliberately unnormalised texts?

For example, when documenting my own keyboards, I would want to
distinguish between a keyboard that went to great trouble to output
text in precomposed characters as opposed to one that took the easy
route of outputting text in fully decomposed characters. For a
Tibetan keyboard, it would matter whether contractions were compatible
with the USE (so generally *not* NFC or NFD) or in NFC or NFD.
