I think this is fine for now, though we may need to revisit.

Metadata about metadata is the named graph approach that I know Dan 
Brickley and John Barstow were both thinking about. For example, let's 
say you register a metadata graph in the manifest like so:

  <manifest:file-entry
	manifest:media-type="application/rdf+xml"
	dc:source="http://ex.net";
	manifest:full-path="meta.xml"/>

The dc:source attribute is metadata about the metadata graph. But there 
are other ways to describe it using a URI.

But it's not something to worry about for your list, since it's trivial 
to support it with the system I've been advocating. It just requires a 
convention to assign a URI to the file.

"Neglected" in the sense that it doesn't matter to this particular 
focus (associating document content with metadatq).

The only thing I would say is be careful about thinking too much about 
xpath for this.

For now let's just worry about what document objects we need to support 
making metadata statements about.
