Joe,

And this aligns with the scope of the Audio WG ...

... and the "1.2 Out of scope" section
http://www.w3.org/2011/audio/charter/Overview.html

"This group will not work on audio representation markup during this 
charter period; discussions of music notation formats will continue in 
the Audio Incubator Group."

Best,

Thierry.

And although there are ways of embedding explicit real-time performance data into MusicXML, this feature is optional and in practice is not usually included in MusicXML documents.

Different applications are free to do this using quite different approaches and a lot of judgment calls come into play. It would be very challenging to standardize such a thing.

Having the Web MIDI API and the Web Audio API together will allow MusicXML-aware applications and libraries to finally be implemented on top of web standards.

The Web MIDI API seeks to solve the technical restriction of having access to external/internal MIDI devices available to the computer. The API doesn't, for example, allow playback of standard MIDI files out of the box, but it does enable you to send messages to MIDI devices so that user-side standard MIDI libraries can have an output target for the data they read.
