    <abstract>
      <t>This document specifies Multiple Ethernet - IPv6 mapped IPv6
      address(ME6A) spefification. ME6A is an Ethernet-mapped IPv6 address
      with a plane ID. Unique allocation of plane id value enables duplicated
      MAC address unique in IPv6 address space. This address may use Ethernet
      over IPv6 encapsulation.</t>
