 * Namespace of available {@code typedef}s inside of an {@link EffectiveStatement}. It holds that statement's
 * {@code typedef} substatements. This constitutes the statament's contribution to the following in accordance with
 * RFC7950 section 6.2.1:
 * <pre>
 *     All derived type names defined within a parent node or at the top
 *     level of the module or its submodules share the same type
 *     identifier namespace.  This namespace is scoped to all descendant
 *     nodes of the parent node or module.  This means that any
 *     descendant node may use that typedef, and it MUST NOT define a
 *     typedef with the same name.
 * </pre>
