The template for sect3.titlepage generates:
<h3 class="sect3">
<a id="{id of sect3}" name="{id of sect3}"></a>
<h4 class="title">
<a id="{id of sect3}" name="{id of sect3}">i{title of sect3}</a>
</h4>
</h3>
resulting in double definition of the same id, which is a validity error
in XML documents.
Replace with the same template as for sect2, using h3 instead of h2.
The template named generate-basic-index in
{docbook-xsl}/xhtml/autoidx.xsl has a bug that generates a div element
with a wrong xmlns:xlink attribute. See
https://github.com/docbook/xslt10-stylesheets/issues/239.
Rather than fixing docbook-xsl, which would work only in LFS (but we
want to be able to render on other distros), copy the faulty template
to our customization files (lfs-index.xsl), so that this one is used.
We can also simplify it a lot since we don't need all the cases
covered in general docbook-xsl.
Also remove the sed for this bug in the Makefile.
Remove python2 remnants from six and make som minor text changes.
Remove legacy elements from lfs-xsl stylesheet.
Minor text change in pip3 xinclude file.
- with a slight change of the css stylesheet, allows having the glossary
title in the same style as the others
- tested with docbook-xsl 1.78.1, 1.79.1, 1.79.2
