When implemented this method resolves a unigue combination of
function URI, function name and number of arguments into an instance
of
XmlExternalFunction
used to implement an XQuery extension
function. If the URI, name and arguments cannot be resolved NULL is
returned. It may return a singleton or a new instance. Memory
management of the returned object depends on the implementation of
the XmlResolver and the
XmlExternalFunction
instance. Singletons are usually owned by
XmlResolver while new instances must be
deleted by XmlExternalFunction::close().
If a transaction is in force, a pointer to the XmlTransaction object; otherwise, NULL.
The XmlManager object associated with the operation.
