No, it was just an example. I didn't want rovide examples of every
possible use of the document() function, so I picked the one that in my
opinion was the most useful you are going to be referring to a document
multiple times, it makes more sense to only call document() once and bind
the n set it returns to a variable, then refer to that variable.
Like any other function, it returns an object of one of the type ode-set,
number, boolean, string, result tree fragment. You know that it returns a
node-set, so you can use it anywhere wher u expect to see a node-set. So
it could be the first location step in an XPath expression. I am not aware
of any XSL process (aside from IE) that would have any trouble with that.
