I think the confusion comes from me mixing my response. Discussion of
proper DOCTYPE and the necessity of the <?xml version="1.0" ?> directive
are about what makes a valid XHTML document

But, as I read more, I came to find that the HTML WG suggests, and
apparently all browsers implement, ignoring those directives and instaead
caring only about the Content-Type header/directive. So if you have that
header/directive in Xiphos, then try updating that to the appropriate
"application/xhtml+xml" and see if that fixes Xiphos/WebKit's behavior?
