Well, as I said, it just depends on the version of libxml2 that you are using.

>>> from lxml import etree
>>> print "lxml.etree:       ", etree.LXML_VERSION
lxml.etree:        (2, 2, 2, 0)
>>> print "libxml used:      ", etree.LIBXML_VERSION
libxml used:       (2, 6, 32)

>>> from lxml.html import fromstring

>>> document = fromstring("""<!DOCTYPE html PUBLIC "-//W3C//DTD
... XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"><html
... xmlns="http://www.w3.org/TR/1999/REC-html-in-xml"

... lang="en"><head><title>Help!</title></head><body><p>My namespaces are

... """)

>>> print parser.tostring(document)
<html xmlns="http://www.w3.org/TR/1999/REC-html-in-xml"
xmlns:cs="http://something.com/cs" xml:lang="en"
lang="en"><head><title>Help!</title></head><body><p>My namespaces are
