Do we really feel that it is useful to include Patient.animal as a part of the base spec? That is a modifier element, and in practice, I expect nearly all (human-centric) implementations will ignore the fact that it is a modifier, and thus not strictly be spec-compliant. If everyone is going to intuitively do the wrong thing per the spec, that seems like a problem with the spec. My suggestion is to remove Patient.animal from the core spec and make it standard extension.
