Indeed. And since @version isn't allowed in HTML5, it's a fairly safe
bet that a document using it is intended to be XHTML 1.1. ;)

I also think expecting XHTML5 from "application/xhtml+xml", like
browsers will do, is the default, and only if it can be figured out
(checking doctype if possible, or @version, or perhaps presence of
@xmlns:*) is XHTML 1.1 to be chosen.
