Oh, there's a problem in this case.  At least two people so far have 
independently read this text to mean that in this testcase:

     * { color: red }
     #foo { color: green }
   <div id="foo">Text</div>
   <div id="foo">Text</div>

should have a green first line and a red second line because the 
requirement that IDs be unique is normative CSS requirement...

I'm not asking for us to do this for every sentence.  I'm asking for us 
to do this for a particular part of the spec that is actively confusing
