If it's the number one question, then maybe that's tell you something  
about your implementation. If you get an xpath context from a  
document, shouldn't that xpath context have a default namespace which  
is the document's default name space?

My function works and yours didn't, how is that broken? Mine is also  
simpler to use and faster.

XML isn't the only language with namespaces. C++ has them, Java has  
them and even a class can be considered to be a "name space". In both  
these languages I don't need to explicitly state the full name. Why  
should XML be different?

In C++ I can do this:

string s = "hello";

Or:

std::string s = "hello";

But you think you know more about how name spaces should be used than  
the makers of Java and C++?

OK then.

Except that it is a copy, because it's going into a document with the  
same name space.
