'Language system' (not 'language') in the OpenType specification actually 
means
*writing* system, i.e. a particular set of orthographic/typographic 
conventions
associated with the use of a particular script. 'Language system' is a
misnomer -- an historical artifact of the incomplete understanding of the
format's original designers --, and it has caused all sorts of confusion,
especially among people who assume that the OT 'language system' tags must 
have
some relationship to things like NLS tags. There is no necessary relationship
and, indeed, it is possible to conceive of a user wanting to apply, for
instance, the typographic conventions of German to a language other than 
German.

I've suggested to Microsoft and Adobe that the term used in the spec should be
changed, or at least annotated.
