/**
`DynamicSchema` are types that provide `NSManagedObjectModel` instances for a particular model version. CoreStore currently supports concrete types:
- `XcodeDataModelSchema`: describes models loaded from a .xcdatamodeld file.
- `LegacyXcodeDataModelSchema`: describes models loaded directly from an existing `NSManagedObjectModel`. It is not advisable to continue using this model as its metadata are not available to CoreStore.
- `CoreStoreSchema`: describes models written in `CoreStoreObject` Swift class declarations.
