Integral models in unramified mixed characteristic (0,2) of hermitian   orthogonal Shimura varieties of PEL type, Part II
  We construct relative PEL type embeddings in mixed characteristic (0,2) between hermitian orthogonal Shimura varieties of PEL type. We use this to prove the existence of integral canonical models in unramified mixed characteristic (0,2) of hermitian orthogonal Shimura varieties of PEL type.
