Best way of adding external funcs to XPath S9

What is the recommend way of adding an external (extension) function to XPath. I
read the page http://www.saxonica.com/documentation/extensibility/functions.html And I
have that working in Xquery, but it doesnt describe how to do this in pure XPath. I'm
using the S9API XPath. Can I use the declareNamespace() from XPathCompiler ? Is that the
correct way of doing it ? Or is there some other way of registering extension functions.
My fallback position is to use XQuery but I'd rather not in this case expose the ability
for users to enter in xquery expressions where XPath expressions are required. Thanks
for any suggestions.

Extension functions in XPath work the same way as in XQuery. The only difference is
that you can't declare the namespace from within the query prolog, you have to do it
externally from the API using declareNamespace().
