id="112233" and id="-2bar" are actually totally valid IDs in HTML5, as
far as I can tell:
http://dev.w3.org/html5/spec/Overview.html#the-id-attribute
So I'd think CSS should definitely allow those unescaped, unless
there's a reason I'm missing to require the escaping. (Clearly it
does need to impose stricter requirements than HTML5 imposes, like not
allowing ambiguous characters such as "." or ">" unescaped.)
