+    <!-- The variable $pass3 is not really needed, but is left here to
+         make it easier to write debugging code. Remember, though,
+         that if you want to see what the intermediate stages look
+         like you cannot use <result-document>, because this template
+         is called from within a variable defintion. You can get
+         around this by outputing each intermediate stage ($pass1 &
+         $pass2) into the output file in addition to the final stage
+         ($pass3). This makes for great debugging, but also for a
+         useless output RELAX NG schema, of course.
