The valid return types from an XQuery query are XML schema types while the valid return types from an XPath 1.0 query are a boolean, string, number, or nodeset (is there one I've forgotten?). So the question is if the XML:DB API promotes the results of a query to their own type will they be XPath 1.0 types, XML schema types or some hybrid?
