Just for the record. The code base actually evolved in sync with the way 
we highlight. This can be emulated with

\usemodule[scite]

\starttyping[option=TEX]
....
\stoptyping

This also supports nesting of mp and lua and some more (not all nesting 
makes sense). It's kind of the reference for context syntax 
highlighting. (We do have specific highlighters for xml, pdf, sql .. the 
things i needed so to say).

The information  for this is part of the context distribution, like 
commands, keywords, classifications, etc. It comes in editor specific 
support and in xml files that describe the commands etc. If needed 
additional files can be generated (we do it for some editors with 
 >mtxrun --script interface) but I have no clue what data emacs needs.
