Notes on the Saxon implementation

Saxon effectively executes the doc() function and returns true if it succeeded; as a side-effect, the document will be available in memory for use when the doc() function is subsequently called with this URI.

A user-supplied URIResolver is invoked in the same way as for the doc() function.
