No doubt that there could be orthogonal sets of rules, and in such cases it
may be a nonsense to try to transform between them. Though given the
activity around e-commerce languages and XSLT type transformations there is
probably a family of transforms that would be useful to do. I suppose it
would have to be up to the user to decide whether to initate the tranform or
not.

That was bothering me also, but I thought I'd send up the kite to see if it
would fly. I thought there should be something smart that one could do with
meta-data + meta-data.
I suppose it is equivalent to having a relational database with schema-a and
asking it to export and then load into schema-b.
Tricky :)
