Staff-change lines

[olin256]

Is it possible to notate staff-change lines in MusicXML like in LilyPond? The only meaning of this is to indicate voice leading between staves, no glissando etc.

I don't think it exists at this point. I'm on low internet while traveling for one more day but I wanted to not look like I was ignoring this altogether.

I use lines like this (usually with arrows) both to cross staves and to indicate crossed voices (in early music mostly in whole notes and breves where stems aren't always there to clarify) so a more general solution showing voice continuity might be best. More soon.

Currently you use a bracket element for this, e.g. <bracket line-end="none"/>. But this doesn't convey the staff changing semantics of this line compared to other lines.

Adding semantics to differentiate meanings for common graphical symbols (whether glyphs or lines) seems to me better-suited to MNX than to MusicXML. If we did want to start adding them to MusicXML, there's a lot of guitar notation that I would give priority over this.
