The key used for ModelAccessorsRegistry map is the URI of the first odesign resource of the resource set. It is strange.
For example, at a session creation, there is no Viewpoint selected, the key is "". For the same session, after Viewpoint selection, the ModelAccessor returned by the registry will not be the same (because the key is no longer "").

Furthermore, in some condition, this causes strange effect. For a session "sessionA" with an editingDomain using resourceSet "rsA", the result with these 2 expressions is not the same:
* PermissionAuthorityRegistry.getDefault().getPermissionAuthority(rsA);
* sessionA.getModelAccessor().getPermissionAuthority();

I have not simple reproduction use case. I'll try to add it later.
