Good question. Different programs have more (or less) success at
handling this. L3Lab seems to have no trouble with it. LDLite usually
does ok, but not always (unfortunately, I don't have an example).

There's no special syntax, the rendering program would use the first
FILE encountered in the sub-mpd as the primary model from that file.

It gets tricky here -- files are only loaded as they are referenced, but
renderers may retain loaded FILEs in memory, and later reference them
(even after the sub-mpd is exitted).
I think the MPD standard should include scoping/visibility rules, so
FILEs in an mpd are only available from within that MPD, not from other
DAT/LDR/MPD files.
