[Po4a-devel] comments in XML

I have Guide-file with header like this:

<?xml version="1.0" encoding="UTF-8"?>
<!-- 
$Header: /var/www/www.gentoo.org/raw_cvs/gentoo/xml/htdocs/doc/en/xml-guide.xml,v 
1.64 2006/05/11 17:07:41 rane Exp $ -->
<!DOCTYPE guide SYSTEM "/dtd/guide.dtd">

<guide link="/doc/en/xml-guide.xml">
<title>Gentoo XML Guide</title>

<abstract>
This guide shows you how to compose web documentation using the new 
lightweight Gentoo GuideXML syntax.

And I need preserve commented cvs "$Header: $" and warnings about license.
I know, it's possible make with addenda, but this is not Perl-way :).
I found temporary fix for this, like a commenting out this string in Xml.pm:

f_extract       => \&tag_extract_comment,

but this made other bug - program crashes when try parse commented tags.

How work functions for XML-header, may be it useful for comments?
