The thing that tends to confuse people about boolean operations in XSLT is that, although the *operators* are and behave as you would expect, the *operands* aren't always what programmers from other backgrounds assume them to be, especially where one or both of them is a node-set rather than (the equivalent of) a string. So when Boolean expressions return apparently odd results, people suspect there's something odd about the operators (or maybe their associativity), when the problem lies in what they're evaluating.
