I read this as describing the four column, so abstract syntax, not 
concrete syntax.

Example 1 says "the serialized graph will consist of the single 
triple,<s>  <p>  <o>."  I thought the point of Example 2 (aside from the 
statefulness of actually getting the graph) was that

<http://example.org>  {<s>  <p>  1. }
<HTTP://example.org>  {<s>  <p>  2. }

was impossible because the graphs are closed.

Sandro - did I misread it?
