     <p>The HTML mixed mode depends on the XML, JavaScript, and CSS modes.</p>
 
+    <p>It takes an optional mode configuration
+    option, <code>scriptTypes</code>, which can be used to add custom
+    behavior for specific <code>&lt;script type="..."></code> tags. If
+    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>

     <p><strong>MIME types defined:</strong> <code>text/html</code>
     (redefined, only takes effect if you load this parser after the
     XML parser).</p>
