Tagging MusicXML and other engraving files

[mscuthbert]

Would there be interest in adding a Category tag for MusicXML Available and perhaps other engraving formats? I've found some amazing files that demonstrate engraving aspects that don't appear anywhere else on the net in CC or other free formats, but they're rather hard to find. MusicXML seems the highest priority, but other formats would work too. If there is interest, I'll start tagging the pages as I find them. Thanks! Myke
