No, it was just an example. I didn't want to provide examples of every
possible use of the document() function, so I picked the one that in my
opinion was the most useful. If you are going to be referring to a document
multiple times, it makes more sense to only call document() once and bind
the node-set it returns to a variable, then refer to that variable.

Like any other function, it returns an object of one of the types: node-set,
number, boolean, string, result tree fragment. You know that it returns a
node-set, so you can use it anywhere where you 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 processors (aside from IE) that would have any trouble with that.
