Attached is a patch, which adds this music function to LilyPond and 
musicxml2ly, together with a conversion rule, docs changes (I don't know 
French, so please check if the text there needs to be changed, too!), updated 
regression tests, etc.

I choose ottava as the name, since that's the musical term. However, there 
might arise some confusion with the function \octave, which I propose to 
rename to \octaveCheck (similar to \barNumberCheck) to make its purpose 
clearer.

What do you think about this?

Cheers,
Reinhold
