1.  Introduction

   This document defines a new mobility option, the Access Network
   Identifier (ANI) option and its sub-options for Proxy Mobile IPv6,
   that can be used by the mobile access gateway to signal the access
   network information to the local mobility anchor.  The specific
   details on how the local mobility anchor uses this information are
   out-of-scope for this document.  These mobility options are optional
   and are not mandatory for the Proxy Mobile IPv6 protocol.

Nit: Last sentence: "optional" and "not mandatory" are the same thing on my book.

Strictly speaking PEN numbers are not limited to 4 bytes. However you have a registry for types of identifiers, so a new value can be allocated for bigger-than-4-bytes PENs.
