[vo-dml] Clarification on composition rule..

[CresitelloDittmar, Mark]

Gerard,

I'd very much appreciate feedback on the transform model if you've reviewed
it.. probably on a separate thread would be best.
This model is getting a lot of real-world exercise, being applied to both
the AST and gWCS libraries.

So.. two compositions to the same target is supposed to be invalid?
