Implement saxon:has-local-namespaces. The function takes an element node as input and returns
true if (a) the element is parentless, or (b) the parent is a document node, or (c) the
element has namespace declarations or undeclarations that differ from those of the parent
element (that is, if its in-scope namespace bindings are different from those of the parent
element).
This function is provided for use by the XSLT-compiler-in-XSLT, so that it can decide efficiently whether to generate an "ns" element containing namespace bindings in the SEF file.
