Re: RE: The limits of XML mean the limits of my data world

I practise music in a baroque group, and we all use MusicXML to exchange 
scores.

Professional musicians use Finale (a commercial product), but simple 
amateurs use MuseScore, which is open source.

But yes, XML allows to extend the limit to my music world !

Best regards,
Christophe
