Or, to take an example from the TMQL-spec:

    [...] tuple expression can be used to find all evil people in the

      // person -- // evil-evildoer

The expression does not produce a reliable result until we have
defined some ordering either within the TMDM->TMRM mapping or
somewhere else (like the document order of the XML data model).

Or do I make a mistake here?
