For example, in Trac you can see that the generated output (XHTML) looks
like this:
view-source:http://trac.edgewall.org/wiki
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

Not sure what you're doing exactly on your side... a reproduction
example would help.
Do you have Babel installed?
