Although technically it is perfectly o.k., I wonder whether the SPARQL 
should not be made a bit different just to emphasize the point. At least 
_not_ use the same bnode symbols, ie, something like:

ASK WHERE {
_:x
     <http://xmlns.com/foaf/0.1/name>
        "Manu Sporny" .
  _:x
     <http://xmlns.com/foaf/0.1/knows>
        _:y .
_:y
     <http://xmlns.com/foaf/0.1/name>
        "Ralph Swick" .
}

or even radically reformat it:

ASK WHERE {
[ <http://xmlns.com/foaf/0.1/name> "Manu Sporny" ;
   <http://xmlns.com/foaf/0.1/knows> [
	<http://xmlns.com/foaf/0.1/name> "Ralph Swick".
   ]
].
}

For a not-really-initiated reader the current setup might suggest that 
by simply taking over the same symbols from the original, RDFa source it 
is all right...

Cheers
