getEnclosingCTDefinition() is only going to work for local element declarations. A faster route than starting from the XSModel (which you can only retrieve from the validation root anyway) would be to get the type definition [1] from the ElementPSVI and walk to the XSParticle from there. Note that when there are multiple XSParticles whose term is the same element declaration determining which XSParticle matched requires that you also look at the preceding elements in the instance document. In general you also need to pay attention to wildcard particles (XSParticle.getTerm() -> XSWildcard).
