Joe, I agree this is important for implementing sample-playback synths (SoundFonts, etc.).  The one point I'd like to make sure we figure out is how to deal with the sample data *after* the loopEnd attribute.  For example, in SoundFonts the loopEnd is often (but not always) set to end of the total sample data.  But when it's not, upon receiving a note-off command, the loop is expected to "exit" and proceed with sample playback all the way through to the end of the sample data (finally playing the sample data after the loopEnd).
