We will almost certainly have to use an "obsolete permitted doctype
string" to get lxml / libxml2 to output xhtml correctly. This means
the intersection of the lists in
http://svn.gnome.org/svn/libxml2/trunk/xmlsave.c and
http://dev.w3.org/html5/spec/Overview.html#obsolete-permitted-doctype-string
- xhtml 1.0 strict.
