You've declared text/html, so we need to apply HTML rules.  So there's no

That's XHTML 1.1, which is not a valid HTML doctype.  The validator should
complain.

That is, typos aside, valid XML and XHTML.  If you send it with an XML or
XHTML Content-Type, you get the behaviour you expected (or report a bug).
