Consider as a simple testcase test.xml:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"
  "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd">
<book/>

I get:

$ /usr/bin/docbook2x-texi test.xml
error : xmlAddEntity: invalid redeclaration of predefined entity
[...]

"xmllint --loaddtd --valid test.xml" does not show any redeclaration
of predefined entity issue. So this seems to come from docbook2x-texi.

Hi!

TL;DR the warning output is from libxml2 and the issue is caused by
content of file /usr/share/docbook2X/xslt/common/text/l10n-set.xml
that is indeed part of package docbook2x.

I have filed a report for this upstream with both a detailed analysis
and a patch at https://sourceforge.net/p/docbook2x/bugs/25/ .

I have pushed that very patch in Gentoo just now. Would be cool to
stop seeing that warning again and again also in Debian and Ubuntu.
Thank you!

Best, Sebastian
