Stefan,

As far as TMQL is concerned, our current plan is to support output in
the form of

   - lists of tuples (like in good'n'old SQL),
   - XML documents (actually infoset structures) like good'n'new XQuery, and
   - TM instances like ??? (hey, something new :-)

Containment for lists of tuples can be defined rather natural.  I am
not sure about a containment in XML (subtrees?), there could be many
ways to define this.

For TM output, we would have to define finally what 'fragments' or
'submaps' are. Not a big deal, I guess once we have a formal model.

BTW: Anyone working (have worked) on this, please feel free to send me
a link; I think it is overdue to collect the approaches on a dedicated
page. I promise to republish this as TM!
