   - Means _semantic_ non-null types may be treated as if they were _strict_ non-null types for type generation - see `graphql-sock` below.
 - [`graphql-sock`](https://github.com/graphile/graphql-sock) - takes a semantic nullability schema SDL and converts it into a traditional SDL either by stripping semantic-non-nulls (`semantic-to-nullable`), or by converting them to strict non-nulls (`semantic-to-strict`).
