Okay ... I'm not saying this is wrong (you know this stuff better than I
do, of course), but why do you need to pass a namespace, when XSLT
parameters don't have namespaces? And why is it an empty string, when
null namespaces for elements and attributes are represented as None?

Inquiring minds want to know.
