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.
