I always serve my pages as application/xhtml+xml except when an honest 
bot asks for the page (Twitter, some accessibility testers, Google Page 
Speed, all have trouble with real XML - often either screwing up with 
the self-closing script tags or parsing it correctly as XML but adding 
junk after the closing tag somewhere in their processing)

I've not tried as I don't think browsers would know what to do, but one 
should be able to add other XML namespaces to html5 served as proper 
XML, no?

That's how we had to to MathML circa 2000 before HTML5 (and then if I 
recall only Mozilla knew what to do with the MathML) - the same thing 
should work if browsers knew what to do with MusicXML or whatever.
