	HTML5 explicitly allows for (and gives more or less equal
	standing to) /both/ XML and “classic” HTML markup [1]:

    This specification defines an abstract language for describing
    documents and applications, […]

    There are various concrete syntaxes that can be used to transmit
    resources that use this abstract language, two of which are defined in
    this specification.

    The first such concrete syntax is the HTML syntax.  […]

    The second concrete syntax is the XHTML syntax, which is an
    application of XML.  […]

	Moreover, the HTML5 TR makes certain provisions for the HTML
	syntax, which make it possible to represent a sheer class of
	documents in a form that’d be both syntactically-valid HTML
	/and/ well-formed XML at the same time.  Namely:

	• <element /> may be used to represent any of the void elements;

	• the xml:lang attribute is allowed;

	• and so is xmlns.
