RE: node-set from a string?

You can't do anything with a well-formed XML string until you have
parsed it; and there is no standard way of parsing XML from within a
transformation, so it's better to parse it first and then pass in the
resulting tree.

(Though Saxon 7.1 offers saxon:parse() as an extension function.)

The xx:node-set() function does something quite different.
