It _did_ work like that in our original version, yes. We broke all moby 
collections into Taverna collections of moby simples, using Taverna's 
type reconciliation layer to reconstitute these into moby collections if 
required or to iterate over services consuming moby simples. A while ago 
we agreed that this behaviour should be retained so if it doesn't do 
that now it's a bug.
