I should stress that my opinion isn't the last word on the matter. Unless you want to withdraw the suggestion, it will be considered by the working group as a whole.

Hi Michael,

That wasn't really the response I was after, but thank you for the suggestion and taking the time to look at the matter.

However, for a user of XPath, I think providing the operator that directly translates to the concept a user might be looking for, rather than a 'logically equivalent' operator, is a nice thing to do. It seems a simple enough translation, but if I can spare my business users of XPath from needing to make one more small leap in their boolean algebra cogitations, then I'd be happy to do so.


Well, you can always wrap it in a function

declare function f:xor($a as xs:boolean, $b as xs:boolean)  as xs:boolean {
    $a != $b
}
