/**

`DynamicSchema` are types that provide `NSManagedObjectModel` instances for a single model version. CoreStore currently supports the following concrete types:
|
|
- `XcodeDataModelSchema`: describes models loaded from a .xcdatamodeld file.
|
|
- `UnsafeDataModelSchema`: 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 for `CoreStoreObject` Swift class declarations.
