Yes - it is possible to use a separate services for the transformation. In the 
above I was just trying to indicate that it *could* be done in the same service, 
not that it had to be.

The important part of what I was discussing is simply that the transformation 
needs to be described by the metadata. I was not actually advocating any 
specific way to implement the data retrieval.
