ISSUE-463

See comments for 5.1.3 (incorporated by reference).

Typo: "in the last three cases" should be "in the third case".

Invalidating an entity due to a state change is going to be difficult for some people to accept, even though it may not be strictly accurate from a rigorous philosophical point of view (not all adopters of PROV will use the model this way). In fact, if this definition is applied consistently throughout the spec, then all entities will have infinitesimally short lifespans and examples (such as the car relocation example in 2.1.1) will become extremely complex. It might be worthwhile adding a section to discuss topics related to entity state, creation, etc. This would provide a way to retain these more complex points while simplifying the examples used throughout the rest of the spec.

Is it possible for entities to become temporarily unavailable (e.g., for usage)? If so, a state model for entities might be helpful.
