+
+     <li>Dropped the &lt;url-token> production for the non-ultimate
+      arguments. This was fundamentally ambiguous with the keywords, and is
+      unnecessary complexity.
+
+     <li>Added the ability to declare the directionality of an image, so it's
+      automatically inline-direction flipped when placed in an
+      opposite-directional context.
