Implement saxon:has-uniform-namespaces. The function takes an element node as input and returns
true if it can be guaranteed that all descendant elements have the same namespace context as
the target element. (If the result is false, there may or may not be descendant elements
with new namespace declarations or undeclarations.)
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.
Currently returns false for any non-TinyTree element.
