+      	<h2>Differences from Previous TriG</h2>
+        <p>This section describes the main differences between TriG, as
+defined in this ddcument, and the 
       	<ul>
-      		<li>No support for optional = graph naming operator or optional "." after each graph. N3 compatibility not supported.</li>
-      		<li>Graph labels do not have to be unique within a TriG document. Graphs from reused labels are unioned.</li>
-      		<li>Multiple unlabled graphs in the same TriG document are unioned to form the default graph</li>
+          <li>Syntax is aligned to the Turtle [[!Turtle]] recommendation
+            for RDF terms.</li>
+          <li>Graph labels can be blank nodes.</li>
+          <li>The default graph, or sections of the default graph, do not
+            need to be enclosed in <code>{</code> ... <code>}</code>.</li>
+      	  <li>No support for optional <code>=</code> graph naming operator 
+            or optional "." after each graph.</li>
+      	  <li>Graph labels do not have to be unique within a TriG
+              document. Reusing a graph label causes all the triples
+            for that graph to be included in the resulting graph.
+            Sections with the same label are combined by set union.</li>
+          <li>Keywords <code>BASE</code>, 
+            <code>PREFIX</code> (see also [[!Turtle]) and 
+            <code>GRAPH</code> are introduced.
