Load XQuery functions from an input stream. As this function is supposed to work with Saxon HE, this method allows only for loading full XQuery modules and not for XQuery libraries.

Parameters:

aXQueryIS - The Input Stream to read from. May not be null. Will be closed automatically in this method.

Returns:

A non-null MapBasedXPathFunctionResolver containing all loaded functions.

Throws:

net.sf.saxon.trans.XPathException - if the syntax of the expression is wrong, or if it references namespaces, variables, or functions that have not been declared, or any other static error is reported.

IOException - if a failure occurs reading the supplied input.
