But should there not be some (possibly user-overridable) relationship
between an NLS or similar tag (e.g. "lang" in HTML or xml:lang) and one of
these so that a browser or word-processing app that knows what "language"
(e.g. what RFC 3066 tag) is applied to the data can tell the
layout/rendering sub-system what OT "language-system" tags to apply
(assuming some API exists to do so)? Surely that is where we want to move
toward.
