 * The base class for `TableKeysSchema` and `ModelSchema`. This class and its subclasses currently
 * only serve to organize schema-related types, validation methods, etc., but may be used to create
 * schema instances in the future. This is currently not the case, as schema attributes would need
 * to be nested under an instance property (e.g. `this.attributes`), which would require a lot of
 * refactoring. If/when this is implemented, schema instances would also be given "metadata" props
 * like "name", "version", "format", "schemaType", etc.

     * 2. Ensure a valid "type" is specified for all attributes.
     * 3. Ensure "map", "array", and "tuple" attributes include a valid "schema" config.
     * 4. Ensure "enum" attributes include a valid "oneOf" config.

     * @param schemaType - The type of schema being validated ("TableKeysSchema" or "ModelSchema").
     * @param name - A name to identify the schema in any error messages (defaults to "schemaType" if not provided).
