Re: SOURCE test case sketches from users, please?

I coudln't execute either - 'whom' is bound to a bNode from <aliceFoaf.n3> 
and so is different from all bNodes in <bobFoaf.n3>. Carrying over the 
identifying 'mbox' works.

The query in rq23 is

PREFIX data: <http://example.org/foaf/>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>

SELECT ?mbox ?age ?ppd
FROM   data:aliceFoaf data:bobFoaf
WHERE
   SOURCE data:aliceFoaf
   {
     ( ?alice foaf:mbox <mailto:alice@work.example> )
     ( ?alice foaf:knows ?whom )
     ( ?whom foaf:mbox ?mbox )
     ( ?whom foaf:PersonalProfileDocument ?ppd )
   }
   SOURCE ?ppd
   {
      ( ?w foaf:mbox ?mbox )
      ( ?w foaf:age ?age )
   }

which works for untrusted graphs.
