Not that I really need to know this, but someone asked this on StackOverflow, and now I gotta know. :)
Is it possible for a plain Xpath 1.0 query to return a "position()" value? I know it can be used in predicates, but that simply results in the found element at that position. I know I can return the "text()" result from an Xpath, but is it not possible to return the "position()" value? If that's the case, I imagine there are other functions that might seem logical to get values from that won't work like this.
