Finding the subject

I just want to check that we agree how the subject is determined in RDFa.  
(Actually, we need another word for subject, since if the predicate is  
 from the  rev attribute, then the about attribute is the object, not the  
subject; let's call it 'abouthood').

In the general case, abouthood is determined by the nearest about  
attribute on the element or its ancestors, or otherwise the URI of the  
document.

For meta and link:

	if the element or its parent has an about, use that.
	otherwise, if the parent has an id, use that
	otherwise, use a bnode representing the parent element.

Examples:

The meta says what it's about:
   <p>
	<meta about="http://www.example.org" property="dc:creator">Pete</meta>
   </p>

The parent says what it's about:

   <p about="http://www.example.org" >
	<meta property="dc:creator" content="Pete"/>
   </p>
or
   <meta about="" property="dc:creator" content="Pete">
       <meta property="title" content="My blog"/>
   </meta>

It's about the parent, which supplies a name:

   <p id="creator">
	<meta property="dc:creator" content="Pete"/>
   </p>

It's about the parent, which doesn't supply a name:

   <p>
	<meta property="dc:creator" content="Pete"/>
   </p>

Earlier we had the following.

   <link rel="index" href="index.html">
     <meta property="title">The Index</meta>
   </link>

in which it was about the href.

Do we agree that that case is no longer so?
