-    given, it should hold an array of <code>{matches, mode}</code>
-    objects, where <code>matches</code> is a string or regexp that
-    matches the script type, and <code>mode</code> is
-    either <code>null</code>, for script types that should stay in
-    HTML mode, or a <a href="../../doc/manual.html#option_mode">mode
-    spec</a> corresponding to the mode that should be used for the
-    script.</p>

-        <li><code>wordCharacters</code>, a regexp that indicates which

-      (such as <code>br</code>) do not require a closing tag.</dd>
-      <dt><code>alignCDATA (boolean)</code></dt>
