Even better: an example you can compile, which I was working on just before 
getting your e-mail... not exactly a tiny example, but I needed to force the 
example to cross a system boundary.

What I get: Two bars in the first system. The ossia staff (correctly) hides the 
staff lines in the first bar, but displays the clef and time signature at the 
system's left boundary -- free-floating, visually anchored to nothing. 
Everything else is fine.

What I want: Ideally, the "free-floating" clef and time signature should 
display just left of the bar line to m2 (as if there were a clef and meter 
change in that bar). It would be really nice to have the staff lines extend 
backward just enough to cover that space.

Un-comment these lines --

%%%    \remove "Time_signature_engraver"
%%%    \override Clef #'transparent = ##t

-- and the free-floating symbols disappear, but the clef and time signatures 
disappear from the end of the first system and all of the second system, where 
they are needed.

Or, we could back up a couple of steps and I could ask, what's the orthodox way 
to notate this sort of thing? Maybe the standard engravers' reference texts 
have another, better idea? I'm not attached to this specific notation strategy 
-- just looking for something that will be clear and not obscure the meter 
changes.
