[whatwg] 3.5 'xhtml' instead of 'html' prefix

[Anne van Kesteren (fora)]

# @namespace html url(http://www.w3.org/1999/xhtml);
# :not(html|*)[html|repeat="template"],
# html|*[|repeat="template"] { display: none; }

Why is a 'html' prefix used here? It might be clearer to make that 
'xhtml' (or 'foo'; something that can't be confused with the HTML used 
on "today's web").
