Subject: 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.
