markup on top staff of an orchestra piece

[Orm Finnendahl]

Hi,

 in a piece for large orchestra, I need text markup and tempo markings
which only appear on the top staff of the score and each part. I
defined an empty (invisible) staff with removed staff symbol, time
signature, etc., using skips instead of rests, which works well.

Unfortunately as soon as \RemoveEmptyBars is used in the score, the
staff and all markup gets removed.

Is there a way to persuade Lily never to remove that staff without
adding any visual content to it (except for the markup of course...)?
