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. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
