Thanks very much for this info!

Unfortunately, I don't believe the context definition can be added to
the code base.  (I base this on an unsuccessful attempt to add it as
part of the default Voice context during development,)  The reason, as
I understand it, has to do with automatic documentation in the
Internals Reference.  (The issue is that the engraver is written in
Scheme rather than the usual C++.)
