<supports> elements in MusicXML export

[olin256]

Since Audiveris' MusicXML export contains information about beams, staves and accidentals, it should state it explicitly using the <supports> elements in the header like in this example.

For example, MuseScore import behaves differently when beam support is present.

Thanks for this information.
I didn't know we could explicitly declare a support for such basic entities.

Where could we find an exhaustive list of the elements that can be "supported"?
In MusicXML, the "element" attribute is declared as an NMTOKEN type. A bit vague.
In the comments I noticed: beam, stem, accidental, print. What else?

I have no idea if there is any such list. The specs list only those four that you have noticed. This seems to have been an issue already years ago, but seemingly without any progress. Therefore I'd stick to those four only.
