Why is this Unparsed? Why not just use XML?

The only problem I've ever had with Firefox is a bug related to attributes
with namespaces.
Please note that Lift serves XHTML and Firefox is very strict about
validating XHTML. Unless you are serving your static page with a mime type
of application/xhtml+xml, you will not trigger Firefox's heightened
validation.
