Question about @src handling

[Micah Dubinko]

If I am reading the 21 Feb spec correctly, @src now can stand in for the 
subject of a triple in the absence of @about. Can somebody set me 
straight on how this squares with the leading example in section 5.3?

<div about="http://dbpedia.org/resource/Albert_Einstein";>
 <span property="foaf:name">Albert Einstein</span>
 <span property="dbp:dateOfBirth" datatype="xsd:date">1879-03-14</span>
 <div rel="dbp:birthPlace" resource="http://dbpedia.org/resource/Germany";>
   <span property="dbp:conventionalLongName">Federal Republic of Germany</span>
 </div>
 <img rel="foaf:depiction" 
src="http://en.wikipedia.org/wiki/Image:Albert_Einstein_Head.jpg"; />
</div>


In particular, how does foaf:depiction fit in here? Given the image 
resource as a subject, shouldn't it use foaf:depicts?

I have to admit this part of the spec is rather confusing, so I might 
have it wrong.

Thanks, -m
