+
+    <p>The HTML mixed mode depends on the XML, JavaScript, and CSS modes.</p>
+
+    <p>It takes an optional mode configuration
+    option, <code>tags</code>, which can be used to add custom
+    behavior for specific tags. When given, it should be an object
+    mapping tag names (for example <code>script</code>) to arrays or
+    three-element arrays. Those inner arrays indicate [attributeName,
+    valueRegexp, <a href="../../doc/manual.html#option_mode">modeSpec</a>]
+    specifications. For example, you could use <code>["type", /^foo$/,
+    "foo"]</code> to map the attribute <code>type="foo"</code> to
+    the <code>foo</code> mode. When the first two fields are null
+    (<code>[null, null, "mode"]</code>), the given mode is used for
+    any such tag that doesn't match any of the previously given
+    attributes. For example:</p>
+
+    <pre>var myModeSpec = {
+  name: "htmlmixed",
+  tags: {
+    style: [["type", /^text\/(x-)?scss$/, "text/x-scss"],
+            [null, null, "css"]],
+    custom: [[null, null, "customMode"]]
+  }
+}</pre>
+
+    <p><strong>MIME types defined:</strong> <code>text/html</code>
+    (redefined, only takes effect if you load this parser after the
+    XML parser).</p>
