Re: DOCBOOK: sect1 in preface

[Terry Allen <tallen@sonic.net>]

Camille Begnis gave the example

<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook V3.1//EN" >
<book>
    <preface>
        <sect1>
        <para>
        Some content is always required.
        </para>
        </sect1>
    </preface>
</book>          

which is invalid because it lacks the required titles for both
preface and sect1.

regards, Terry
