/*-
 * Reference RFC 6020.
 *
 * The "typedef" statement defines a new type that may be used locally in the
 * module, in modules or submodules which include it, and by other modules that
 * import from it. The new type is called the "derived type", and the type from
 * which it was derived is called the "base type". All derived types can be
 * traced back to a YANG built-in type.
 *
 * The "typedef" statement's argument is an identifier that is the name of the
 * type to be defined, and MUST be followed by a block of sub-statements that
 * holds detailed typedef information.
 *
 * The name of the type MUST NOT be one of the YANG built-in types. If the
 * typedef is defined at the top level of a YANG module or submodule, the name
 * of the type to be defined MUST be unique within the module.
 * The typedef's sub-statements
