If you notice, the specification doesn't say anything about qnames as attribute
or element names either. It just defines syntax for qnames -- it's the CSS
equivalent of a spec that defines xmlns attributes and that says "the syntax
for qualified names is prefix-colon-localpart".

It's up to the Selectors spec to define syntax for selectors, and to say which
parts of the selector are qualified names and which simply strings.

Your CSS rule would, btw, be correctly written as
   [property="dc:title"] { }
because 'property' is not defined as a class attribute. (You can't use the dot
syntax with it.)

Let me know if this addresses your comment.
