I would rather suggest that What WG specs explicitly discourage

from using a doctype on the XHTML side and point out that authors
should
not expect UAs to process the DTD.
Those who want to use entities for input, should parse and
reserialize
as UTF-8 in their own lair and not expose their entity references (or
parochial legacy encodings) to the public network.
The spec has text to this effect in places now; let me know if you
have
more specific text you'd like to see. I don't want to be too
strong, since
if you're using XML, exactly how you do so is the problem of the
XML spec,
not the Web Apps / XHTML5 spec.
At the end of section 1.8 it says:
"These XML documents may contain a DOCTYPE if desired, but this is
not required to conform to this specification."
I'd like to see a note here. Something like this:
Note: According to [XML], XML processors are not guaranteed to
process the external DTD subset referenced in the DOCTYPE. This
means, for example, that using entities for characters is unsafe
(except for <, >, &, " and '). For
interoperability, authors are advised to avoid optional features of XML.
