+     * ####Escaped Interpolation
+     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
+     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
+     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
+     * or binding.
+     *
+     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
+     * degree, while also enabling code examples to work without relying on the
+     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
+     *
+     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
+     * replacing angle brackets (<, >) with < and > respectively, and replacing all
+     * interpolation start/end markers with their escaped counterparts.**
+     *
+     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
+     * output when the $interpolate service processes the text. So, for HTML elements interpolated
+     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
+     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
+     * this is typically useful only when user-data is used in rendering a template from the server, or
+     * when otherwise untrusted data is used by a directive.
+     *
+     * <example>
+     *  <file name="index.html">
+     *    <div ng-init="username='A user'">
+     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "some jerk"; \}\}
+     *        </p>
+     *      <p><strong>{{username}}</strong> attempts to inject code which will deface the
+     *        application, but fails to accomplish their task, because the server has correctly
+     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
+     *        characters.</p>
+     *      <p>Instead, the result of the attempted script injection is visible, and can be removed
+     *        from the database by an administrator.</p>
+     *    </div>
