DOCBOOK: Concrete proposal for #480955: Add coref

[Norman Walsh <ndw@nwalsh.com>]

I suggest we add

<!ELEMENT coref EMPTY>
<!ATTLIST coref
		%linkendreq.attrib;
		%label.attrib;
		%common.attrib;
		%coref.role.attrib;
		%local.coref.attrib;
>

And allow it everywhere that 'co' can occur: computeroutput,
prompt, userinput, programlisting, literallayout, screen, synopsis,
replaceable, and systemitem.

                                        Be seeing you,
                                          norm
