> How can a sequence of anything be an instance of xs:boolean Mike? Just as Xpath 1 doesn't have a "node" type, only a "node set" type, Xpath 2 does not distinguish between a sequence of one item and a single item. Basically _everything_ in Xpath 2 is a sequence. > What's the difference between . and data(.) please? . is the current item (most likely an element node in this case) data(.) is the typed value of that node. so if you are on an element node . instance of xs:boolean will be false as . is an element not a value, and in particular not a boolean. but data(.) instance of xs:boolean will be true if the content of the element is schema typed to be boolean.
