[MEI-L] MEI as XSD or DTD

[Raffaele Viglianti]

I think support for XSD is highly desirable, especially because it's a W3C
recommendation. I agree with Anna that there is generally more support for
XSD than Relax.

On the other hand, I wouldn't mind dropping DTD support since it's arguably
been superseded by schemata and we may run into more problems with it in
the future.

Max, great to hear that Audioveris is adding support for MEI! If you need
XSD, I would recommend generating it from out ODD (our source schema)
instead of converting the rng. You'll need to run the TEI Stylesheets (
https://github.com/TEIC/Stylesheets) to do so, but it's not complicated, I
can provide instructions if you like.

Perry, what about allowing both text and <eventList>? Would it be bad to
allowed mixed content in this case? (Sorry I haven't really looked into
this too hard).

Best,
Raff
