Good points and well articulated, Gordon. Thanks.

I don't know if the full Music XML schema has been published in one consolidated location, so all of the declarations, attributes and tags etc could be 'learned' by parsing it through an application.

I agree that trying to develop a markup language capable of combining so many different music disciplines into one system, is probably challenging.

I'm presuming that 'tidy' and 'xmllint' are Linux items. They sure sound like they are.

Bottom line is that of course it's important that the Music XML support in BIAB works correctly.
