If there is no mapping from the input to H(D,D) to the behavior
of D(D) then H is not even being asked about the behavior of D(D).
H has no obligation to answer questions *THAT IT IS NOT BEING ASKED*
The halting problem specification does not say that a halt decider
can be asked questions. It requires that a description of a Turing
macine and a description of an input to that Turing machine can
be given as an input.
