Appendix structure

[maxwell <maxwell@umiacs.umd.edu>]

We were trying to create a <glossary> as an <appendix>, and ran across
something that seems very odd to me; I'm not sure if it's intentional.

The original structure we tried to use was this:
----------
<appendix version="5.0" xmlns="http://docbook.org/ns/docbook";>
    <title>Glossary of Linguistic Terms</title>
  <glossary>
    <title/>
    <glossentry xml:id="glInfix">
      <glossterm>infix</glossterm>
      <glossdef>
        <para>An infix is an affix that goes inside the word to which it
        is attached.</para>
      </glossdef>
    </glossentry>
  </glossary>
</appendix>
----------

That structure does not appear to validate against the schema, but the
following one does:
----------
<appendix version="5.0" xmlns="http://docbook.org/ns/docbook";>
    <title>Glossary of Linguistic Terms</title>
  <remark>This remark makes the appendix validate</remark>
  <glossary>
    <title/>
    <glossentry xml:id="glInfix">
      <glossterm>infix</glossterm>
      <glossdef>
        <para>An infix is an affix that goes inside the word to which it
        is attached.</para>
      </glossdef>
    </glossentry>
  </glossary>
</appendix>
----------

The only difference is the <remark> element.  Since <remark>s are more or
less comments, it seems odd that they would make a difference in the
validity of the document.  As I'm reading the schema (actually, the verbal
description at http://www.docbook.org/tdg5/en/html/appendix.html), the
<remark> element could be replaced by an <annotation>, <bridgehead>,
<refhistory>, or any of a number of otherwise optional elements; or by a
<section>, <simplesect>, or <sect1>.  Since I *don't* want any of the
section-type elements (I really want the appendix to *just* contain a
glossary), I'm instead using <remark>, which has no effect in my final
(PDF) output.

The <chapter> structure appears to be the same--that is, if I wanted a
chapter to contain just a <glossary>, I would need to insert a <remark>.

Is this intentional?
