I think this is a good start. Little problem though re the use of
@resource to trigger the list behaviour. Consider the following:

	<div about="#eachpeach">
	    <i property="dc:title">Each Peach Pear Plum</i>
	    <ul rel="dc:creator" resource="::Bag">
	        <li property="::member">Janet Ahlberg</li>
	        <li property="::member">Allen Ahlberg</li>
	    </ul>
	</div>
	<div about="#megmog">
	    <i property="dc:title">Meg and Mog</i>
	    <ul rel="dc:creator" resource="::Bag">
	        <li property="::member">Helen Nicoll</li>
	        <li property="::member">Jan Pienkowski</li>
	    </ul>
	</div>

If this were parsed in an RDFa 1.0 parser, it would come out as:

  <#eachpeach>
    dc:title "Each Peach Pear Plum" ;
    dc:creator <./::Bag> .
  <#megmog>
    dc:title "Meg and Mog" ;
    dc:creator <./::Bag> .
  <./::Bag>
    <http://www.w3.org/1999/xhtml/vocab#:member> "Janet Ahlberg" ;
    <http://www.w3.org/1999/xhtml/vocab#:member> "Allen Ahlberg" ;
    <http://www.w3.org/1999/xhtml/vocab#:member> "Helen Nicoll" ;
    <http://www.w3.org/1999/xhtml/vocab#:member> "Jan Pienkowski" .

Any automated agent looking at that would conclude that the two books
have the same authors. Something using, say, @typeof wouldn't suffer
from this problem.
