if an application  does not know protege:thing, it can ignore it.
If a user defines a resource to be a subclass of protege:Thing, protege can 
not ignore this and we have to save that.

However,  i think there is a small missunderstanding: you probably meant 
that #Calendar is a subclass of rdfs:Resource.
Then #Caldendar has to be defined as a subclass of rdfs:Resource, and this 
if of course also serialized in this way.
