Yes. IE6 will go into Quirks if the XML declaration is
present. This url has more details.

It is mandatory in my version also. Here is a snippet
from start_html().
1311 my(@result,$xml_dtd);
1312 if ($dtd) {
1313 if (defined(ref($dtd)) and (ref($dtd) eq 'ARRAY')) {
1314 $dtd = $DEFAULT_DTD unless $dtd->[0] =~ m|^-//|;
1315 } else {
1316 $dtd = $DEFAULT_DTD unless $dtd =~ m|^-//|;
1317 }
1318 } else {
1319 $dtd = $XHTML ? XHTML_DTD : $DEFAULT_DTD;
1320 }
1321
1322 $xml_dtd++ if ref($dtd) eq 'ARRAY' && $dtd->[0] =~ /\bXHTML\b/i;
1323 $xml_dtd++ if ref($dtd) eq '' && $dtd =~ /\bXHTML\b/i;
1324 push @result,q(<?xml version="1.0" encoding="utf-8"?>) if $xml_dtd;
1325
1326 if (ref($dtd) && ref($dtd) eq 'ARRAY') {
Commenting line 1324 stops the "<?xml" line being output.
Changing a module directly is rarely recommended, but you'll
probably want to make this change site-wide. Your line number
will probably be different than mine.
1322 $xml_dtd++ if ref($dtd) eq 'ARRAY' && $dtd->[0] =~ /\bXHTML\b/i;
1323 $xml_dtd++ if ref($dtd) eq '' && $dtd =~ /\bXHTML\b/i;
1324 # push @result,q(<?xml version="1.0" encoding="utf-8"?>) if
$xml_dtd;
1325
1326 if (ref($dtd) && ref($dtd) eq 'ARRAY') {
You'll need to edit again if the admin upgrades or
re-installs CGI.pm. If you can't get to the CGI.pm source
you could copy it locally and "use lib" to use CGI.pm.
I imagine you could also write a module that subclasses
CGI.pm or wraps it to remove the "<?xml" line.
