WADL documentation stylesheet fails with Amazon item search example in WADL spec

I'm considering using WADL, but only if I can generate reasonable
documentation. So as a test of the WADL-to-HTML documentation
stylesheet, I took the "Amazon Item Search" example from the appendix of
the WADL spec and tried to transform it using "wadl_documentation.xls".
The transformation failed with both XMLSpy and Oxygen. The error I
received in XMLSpy is on line 169 of the XSLT: "Function not in
namespace, Error in XPath expression, Function not in namespace". Has
this stylesheet been used at all beyond the Yahoo example? Is it
possible to fix the stylesheet so that it works with the examples from
the spec?
