Another workaround/hack to deal with non breaking spaces. Also some minor adjustments to support the planned AFP renderer

+      Note: This test currently fails because the first non breaking space on

+  <info>
+    <p>
+      This test checks non breaking white space.
+      Note: This test should fail because the first nb space in each line is
+      incorrectly removed. However, the checks below have been adjusted to
+      cater for this defect so this test passes. This has been done to have some
+      test cases which are being run in the test suite for non breaking spaces.
+      This test is otherwise identical to block_white-space_2.xml. Once the problem
+      is fixed this file can be deleted from the test suite.
