Let me try to diagram this.

xml:id
======

document
	paragraph <--- properties


meta:about
==========

document
	paragraph ---> properties


meta:property
=============

document
	paragraph ---> predicate ---> object


So first two establish a subject and allow properties to be attached to 
them (though with different meanings), the last a relationship between 
the subject (the paragraph or document or whatever) and an object.

As an example, there are a bunch of existing fields (author, title, 
etc.) that are in fact properties of the document. Using meta:property 
is a way to make this more generic, and adding meta:about to make the 
subject reference generic (not only about the document or its 
contents).
