We have formalised very simply the l3 condition in our semantics 
document <http://www.inf.unibz.it/krdb/w3c/sparql/>, along the lines I 
was telling yesterday. We added an annotation on variables in queries: 
"Variables may be annotated with a set of elements of RDFT - to 
restrict the possible assignments of variables". And we added a 
condition in the definition of query answer: "if a variable is 
annotated with a set of elements of RDFT then S must map that variable 
to one of these elements". As simple as that.
Please check it out. Comments welcome.
