If I well-understood Grothendieck's homotopy hypothesis, Isabelle/HoTT can
be modeled in Isabelle/HOL, by representing homotopy types via Kan
complexes (we need to develop the theory of Kan complexes in Isabelle/HOL
in this approach). I may be wrong, I am not an expert in this subject. So,
do not believe me. Here some references:
