+  <code>Document</code> objects are presented to the user.</p><p class="note">A tab or window in a Web browser typically contains
+  a <a href="#browsing-context">browsing context</a>, as does an <code><a href="text-level-semantics.html#the-iframe-element">iframe</a></code>.</p><p>Each <a href="#browsing-context">browsing context</a> has a corresponding
+  <code><a href="#windowproxy">WindowProxy</a></code> object.</p><p>A <a href="#browsing-context">browsing context</a> has a <a href="history.html#session-history">session
+  history</a>, which lists the <code>Document</code> objects that
+  that <a href="#browsing-context">browsing context</a> has presented, is presenting, or
+  will present. At any time, one <code>Document</code> in each
+  <a href="#browsing-context">browsing context</a> is designated the <dfn id="active-document">active
+  document</dfn>.</p><p>Each <code>Document</code> has a collection of one or more <a href="#view" title="view">views</a>.</p><p>A <dfn id="view">view</dfn> is a user agent interface tied to a particular
+  media used for the presentation of a particular
+  <code>Document</code> object in some media. A view may be
+  interactive. Each view is represented by an
+  <code>AbstractView</code> object. <a href="references.html#refsDOMVIEWS">[DOMVIEWS]</a></p><p>The main <a href="#view">view</a> through which a user primarily
+  interacts with a user agent is the <dfn id="default-view">default view</dfn>. The
+  <code>AbstractView</code> object that represents this view  is referred to as the <code>Document</code>'s
+  <code><a href="#window">Window</a></code> object. <code><a href="#windowproxy">WindowProxy</a></code> objects forward
+  everything to the <a href="#active-document">active document</a>'s <a href="#default-view">default
+  view</a>'s <code><a href="#window">Window</a></code> object.</p><p class="note">The <code title="dom-document">document</code>
+  attribute of an <code>AbstractView</code> object representing a
+  <a href="#view">view</a> gives the view's corresponding
+  <code>Document</code> object. <a href="references.html#refsDOMVIEWS">[DOMVIEWS]</a></p><p class="note">In general, there is a 1-to-1 mapping from the
+  <code><a href="#window">Window</a></code> object to the <code>Document</code> object. In
+  one particular case, a set of <a href="#view" title="view">views</a> can be
+  reused for the presentation of a second <code>Document</code> in the
+  same <a href="#browsing-context">browsing context</a>, such that the mapping is then
+  2:1. This occurs when a <a href="#browsing-context">browsing context</a> is <a href="#navigate" title="navigate">navigated</a> from the initial
+  <code><a href="#about:blank">about:blank</a></code> <code>Document</code> to another, with
+  <a href="#replacement-enabled">replacement enabled</a>.</p><p class="note">A typical Web browser has one obvious
+  <a href="#view">view</a> per <code>Document</code>: the browser's window
+  (screen media). This is typically the <a href="#default-view">default view</a>. If
+  a page is printed, however, a second view becomes evident, that of
+  the print media. The two views always share the same underlying
+  <code>Document</code> object, but they have a different presentation
+  of that object. A speech browser might have a different
+  <a href="#default-view">default view</a>, using the speech media.</p><p class="note">A <code>Document</code> does not necessarily have a
+  <a href="#browsing-context">browsing context</a> associated with it. In particular,
+  data mining tools are likely to never instantiate browsing
+  contexts.</p><hr><p>A <a href="#browsing-context">browsing context</a> can have a <dfn id="creator-browsing-context">creator browsing
+  context</dfn>, the <a href="#browsing-context">browsing context</a> that was
+  responsible for its creation. </p><p>If a <a href="#browsing-context">browsing context</a> <var title="">A</var> has a
+  <a href="#creator-browsing-context">creator browsing context</a>, then the
+  <code>Document</code> that was the <a href="#active-document">active document</a> of
+  that <a href="#creator-browsing-context">creator browsing context</a> at the time <var title="">A</var> was created is the <dfn id="creator-document">creator
+  <code>Document</code></dfn>.</p><h4 id="nested-browsing-contexts"><span class="secno">6.1.1 </span>Nested browsing contexts</h4><p>Certain elements (for example, <code><a href="text-level-semantics.html#the-iframe-element">iframe</a></code> elements) can

+  in different domains from affecting each other; that is, cross-site
+  scripting is disallowed.</p><p>While this is an important security feature, it prevents pages
+  from different domains from communicating even when those pages are
+  not hostile. This section introduces a messaging system that allows
+  documents to communicate with each other regardless of their source
+  domain, in a way designed to not enable cross-site scripting
+  attacks.</p><h4 id="introduction-5"><span class="secno">8.2.1 </span>Introduction</h4><p><i>This section is non-normative.</i></p><div class="example">
+
+   <p>For example, if document A contains an <code><a href="text-level-semantics.html#the-iframe-element">iframe</a></code>
+   element that contains document B, and script in document A calls
+   <code title="dom-window-postMessage-2"><a href="#dom-window-postmessage-2">postMessage()</a></code> on the
+   <code><a href="browsers.html#window">Window</a></code> object of document B, then a message event will
+   be fired on that object, marked as originating from the
+   <code><a href="browsers.html#window">Window</a></code> of document A. The script in document A might
+   look like:</p>
+
+   <pre>var o = document.getElementsByTagName('iframe')[0];
+o.contentWindow.postMessage('Hello world', 'http://b.example.org/');</pre>
+
+   <p>To register an event handler for incoming events, the script
+   would use <code title="">addEventListener()</code> (or similar
+   mechanisms). For example, the script in document B might look
+   like:</p>
+
+   <pre>window.addEventListener('message', receiver, false);
+function receiver(e) {
+  if (e.origin == 'http://example.com') {
+    if (e.data == 'Hello world') {
+      e.source.postMessage('Hello', e.origin);
+    } else {
+      alert(e.data);
+    }
+  }
+}</pre>
+
+   <p>This script first checks the domain is the expected domain, and
+   then looks at the message, which it either displays to the user, or
+   responds to by sending a message back to the document which sent
+   the message in the first place.</p>
