What steps will reproduce the problem? 1. Simply use "fn:count(//love_element)" What is the expected output? What do you see instead? I am suppose to get back a total number of nodes What version of the product are you using? On what operating system? 1.0.0 vista Home Please provide any additional information below. Error: There is no namespace mapped to the prefix 'fn'.

Basically just trying to call a count function to count how many of the node I am looking for are there. If you have made this use a different namespace instead of fn:count let me know because i am not sure how or if its possible in your current version.

I retract my issue as 'count()' is the prompt term

In XPath 2.0, built-in functions are held in a namespace with fn prefix, but this is not the case in XPath 1.0; they are not in any namespace.

I'm in two minds about whether to support "forwards-compatibility" in this regard, by placing the built-in functions in both the default namespace and "fn". But I am going to change this issue to an enhancement request, to do just that, so it is tracked.

The possible 'fix' would be a forwards-compatibility mode with XPath 2.0. I'm not sure that this is worth the effort.

I would look at contributions which added that, but I don't have time myself, considering the small use-case.
