Bryan, thanks.

The use of PersonalProfileDocument  as a property was wrong anyway and so I have 
redone this example (and the data) to use rdfs:aseAlso and adding typing 
information.  I don't know if that is FOAF prefered practice - If anyone can 
advise me, I'd be most grateful.

PS The query in the editors' draft is currently:


PREFIX  data:  <http://example.org/foaf/>
PREFIX  foaf:  <http://xmlns.com/foaf/0.1/>
PREFIX  rdf:   <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX  rdfs:  <http://www.w3.org/2000/01/rdf-schema#>

SELECT ?mbox ?age ?ppd
WHERE
{
   GRAPH data:aliceFoaf
   {
     ?alice foaf:mbox <mailto:alice@work.example> ;
            foaf:knows ?whom .
     ?whom  foaf:mbox ?mbox ;
            rdfs:seeAlso ?ppd .
     ?ppd  a foaf:PersonalProfileDocument .
   } .
   GRAPH ?ppd
   {
       ?w foaf:mbox ?mbox ;
          foaf:age ?age
   }
}
