+  <info>
+    <p>
+      This test checks external-graphics and the handling of linebreaks.
+      It is unclear at the moment if consecutive images with intervening white space
+      actually should have a linebreak opportunity between them or not. Fop currently
+      takes the "there is no break opportunity" view and the checks test accordingly.
