what is returned by that URL? Do I have to know that your implementation of the way of returning a response has anything to do with SPARQL?

ok, and what would that return on being dereferences?

I don't have enough information to be able to see how this is either a problem or not with the spec.

Well which ones would satisfy the SPARQL query described in the spec

?

ie:

PREFIX : <http://www.w3.org/ns/auth/cert#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
ASK {
   ?webid :key [
      :modulus ?mod;
      :exponent ?exp;
   ] .
}
