Mark, I was not commenting on your stylesheet but on the fact that it is 
always going to be algorithmically uncertain to transform such MADS XML 
fragments into RDF statements if the type of relationship is kept optional.

Of course there is lots of relationship information in the litterals 
that are being connected (for example from "new york" ---> "big apple" 
we can infer the relationship "also referred to as", but this is never a 
mechanical transformation).

But my point is rather simple: no matter how it is encoded, the 
information for all three items of the statement in the MADS XMLSchema 
should be mandatory, or it will be painful, or heuristical, to convert 
it to RDF.
