I do not belive that will work. type source="..." is probably
not intended to look into the (different) datatype namespace.
I hope the Schema people will make this more explicit, e.g.
by changing datatype references to datatype="xxx" attribute.

I think the original idea is that datatype-elements just cannot have
attributes, but I am not sure if that is really a good idea.
