  /** A template trait for traversable collections of type `Traversable[A]`.
   *  
   *  $traversableInfo
   *  @define mutability
   *  @define traversableInfo
   *  This is a base trait of all kinds of $mutability Scala collections. It
   *  implements the behavior common to all collections, in terms of a method
   *  `foreach` with signature:
   * {{{
   *     def foreach[U](f: Elem => U): Unit
   * }}}
   *  Collection classes mixing in this trait provide a concrete 
   *  `foreach` method which traverses all the
   *  elements contained in the collection, applying a given function to each.
   *  They also need to provide a method `newBuilder`
   *  which creates a builder for collections of the same kind.
   *  
   *  A traversable class might or might not have two properties: strictness
   *  and orderedness. Neither is represented as a type.
   *  
   *  The instances of a strict collection class have all their elements
   *  computed before they can be used as values. By contrast, instances of
   *  a non-strict collection class may defer computation of some of their
   *  elements until after the instance is available as a value.
   *  A typical example of a non-strict collection class is a
   *  <a href="../immutable/Stream.html" target="ContentFrame">
   *  `scala.collection.immutable.Stream`</a>.
   *  A more general class of examples are `TraversableViews`.
   *  
   *  If a collection is an instance of an ordered collection class, traversing
   *  its elements with `foreach` will always visit elements in the
   *  same order, even for different runs of the program. If the class is not
   *  ordered, `foreach` can visit elements in different orders for
   *  different runs (but it will keep the same order in the same run).'
   * 
   *  A typical example of a collection class which is not ordered is a
   *  `HashMap` of objects. The traversal order for hash maps will
   *  depend on the hash codes of its elements, and these hash codes might
   *  differ from one run to the next. By contrast, a `LinkedHashMap`
   *  is ordered because it's `foreach` method visits elements in the
   *  order they were inserted into the `HashMap`.
   *

        selectionPointer: true
      });
    </script>

    <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>

    <dl>
      <dt><code>htmlMode (boolean)</code></dt>
      <dd>This switches the mode to parse HTML instead of XML. This
      means attributes do not have to be quoted, and some elements
      (such as <code>br</code>) do not require a closing tag.</dd>
      <dt><code>matchClosing (boolean)</code></dt>
      <dd>Controls whether the mode checks that close tags match the
      corresponding opening tag, and highlights mismatches as errors.
      Defaults to true.</dd>
      <dt><code>alignCDATA (boolean)</code></dt>
      <dd>Setting this to true will force the opening tag of CDATA
      blocks to not be indented.</dd>
