It probably doesn't hurt to mentation it is Daniel's viewpoint that 
XSL-T "canibalize the same namespace". Versioning is a debated topic, and 
that a separate namespace should be used for extensions is one of many 
possible views. In other cases versioning is handled in other ways -- which 
XSL-T is an example of with its version attribute and fallback mechanisms.

Personally, I like XSL-T 2.0 in this regard. I would find it quite unpractical 
to use different namespaces depending on if the function is from XPath 1.0 or 
2.0, or even if it's from XSL-T 1.0 or 2.0. I do not immediately see the 
drawbacks of not using a second namespace(s).

Yes, I think so too.

XSL-T 2.0's functions are in the same namespace as XPath 2.0. As I see it, 
this is by the same principle as 1.0 with the only difference that it is an 
explicit namespace instead of an empty namespace URI, or "none".
