Hi Dileep,

It should be possible to query on versioned compositions but I feel a bit
uncomfortable about using versioned data this way. For event-type
compositions, I would only expect versions to be created as a result of an
error correction, not as part of routine recording. For persistent-type
compositions, new versions are routinely created but only when the previous
version is reallyof little interest e.g summaries, status-tracking.

I'm uneasy about your suggested approach. Can you spell out an example/
