I don't think it should be expected to work. The XPath query service iterates over the collection (with some speedup from indexes) and finds documents matching the XPath conditions. I don't believe that it can join documents. Futhermore, there is no way to indicate in a single XPath expression that one of the terms came from one document (/users/[EMAIL PROTECTED]) and another term came from a second document (/groups/group/@id). The only way this could work would be if the entire collection were considered 1 document, but in this case, either the union document would not be well-formed XML (because it did not have a single root element) or the XPath expressions given in parentheses above would never be matched because they did not include that single root element.
