Any plans to pass the Chrome schema here as well? FWIW, the Win loader already
uses schemas internally... I guess we should use a single one - is that planned
for a follow-up CL?

Yes it is :-) Having a complete PolicySchema for Chrome removes the need for the
schemas-in-registry hack, and also makes support for structured policy easy.

+  service->RegisterPolicyDomain(descriptor);
   return service.Pass();
