[ome-devel] Deprication to Schema

[Josiah Johnston]

The DerivedFrom Element under <Pixels> was created as a temporary  
measure to offer primitive support of derived pixel sets (1). Now that  
DataHistory (2) is implemented, working, and stable, the time has come  
to depricate <DerivedFrom>. It will be removed from the schema as of  
next week unless someone has well reasoned objections.
