I just downloaded and compiled libxml2-2.6.1 and
libxslt-1.0.33 on my Linux box.  This version seems
to be having namespace problems.  Now when I process
any docbook file with the DocBook XSL stylesheets I get
lots of these errors:

-------------------------------------------------------------------
../docbook-xsl-1.62.4/common/af.xml:2: namespace error : Namespace
prefix xmlns for l on l10n is not defined
.sourceforge.net/xmlns/l10n/1.0" language="af"
english-language-name="Afrikaans"
                                                                               ^
../docbook-xsl-1.62.4/common/af.xml:2: namespace error : Namespace
prefix l on l10n is not defined
.sourceforge.net/xmlns/l10n/1.0" language="af"
english-language-name="Afrikaans"
                                                                               ^
../docbook-xsl-1.62.4/common/af.xml:10: namespace error : Namespace
prefix l on gentext is not defined
   <l:gentext key="Abstract" text="Samevatting"/>
                                               ^
etc.
-------------------------------------------------------------------
These errors are repeated for all the other locale files.

But the first file in question (common/af.xml) starts
like this:

<?xml version="1.0" encoding="US-ASCII"?>
<l:l10n xmlns:l="http://docbook.sourceforge.net/xmlns/l10n/1.0"; language="af" english-language-name="Afrikaans">

It sure looks to me like the "l" namespace is defined.

Should I file a bug report?
