An XQL query may return numbers, strings, Date objects or even user
defined data types, which are not nodes in the DOM sense, but
objects. If you wrap the results in tags like <xql:date>, ... you
will get problems with the user defined types and loose type
information.
To me the return values of a query are just a vector of objects in
document orders, of which some happen to be DOM nodes.
