Character entity set for RFC-2629 source xml documents.

     There is no need to invoke this directly from

     the source document itself; just invoke the DTD.

     These are unknown to (X)HTML, so any converter to these

     formats must either substitute these entities

     or invoke this file from the output file.

     Conversion to txt or nroff format will replace

     these entities by the parenthesized text.

     Typical invocation:

                PUBLIC "-//IETF//ENTITIES Other for RFC 2629//EN"

                       "http://xml.resource.org/authoring/rfc2629-other.ent">

       %rfc2629-other;

-->

                                of number="..." attribute

                                of <rfc> element, or to "XXXX")                       -->
