I think this is something that is often overstated.

RFC 2854 notes that "different versions [of HTML] are distinguishable by
the DOCTYPE declaration contained within them", so -- assuming that
XHTML is a "version" of HTML, whatever that means -- it is not incorrect
behaviour to detect an XHTML DOCTYPE and perform version-specific
parsing on the content.

I realise that many popular user agents (especially desktop browsers) do
not do this, but that doesn't make it wrong to do so.
