Placement of lyrics

[axgeertinger]

It would be nice to be able to place lyrics above the staff. I am working on an edition of songs, some of which are notated as piano arrangements without a separate vocal staff. My only option currently is to place the lyrics between the piano's staves, when ideally they should go above the top staff.

So, my request is supporting att.placementRelStaff on verse and/or syl elements.
