As an update to the previous version of the specification I have written a new draft of Automatic transformation between XML documents with different namespaces.

This updated version supports the choice of the user to download only information referenced from the source or only information referenced from the destination.

For example, it allows, when directly transforming from an XML namespace A to an XML namespace B, to download only transformation information at A or only information at B (provided that this data is available at A or at B respectively).
