I think I see it now.  Our README.links says:

<xref>
        use to get chapter/section number from the title of the target
-->     link, or xreflabel if defined at the target, or refentrytitle if target
-->     is a refentry;  has no close tag
        http://www.oasis-open.org/docbook/documentation/reference/html/xref.html

I was not aware that refentry can pull from refentrytitle.  I just
tested it for pg_upgrade, and it worked fine.  I will adjust the release
notes now to use them.  Thanks.
