RE: Extra staves

[Ralph Little]

Woooohoooo! That's just the ticket!
Many thanks Mats!

I missed the meaning of \accepts in the doc and also that you could include
existing contexts in a new context definition by mentioning it.
I did try copying the ScoreContext definition from engraver-init.ly, which
would have worked had it not been for the fact that I missed the \accepts
for the ScoreContext.
Also, you don't seem to need the StaffGroup context for this to work. It
might cause me grief when I come to put the part into a score with other
parts, but we'll see...

Here is the final example and is JUST what I'm after:

Han-Wen and Jan, would it be worth putting this in the Tips and Tricks
section of the manual?

Lilypond just gets better and better!

Many thanks,
Ralph
