+ <p>Each <code>Document</code> has a <dfn>list of animation frame callbacks</dfn>, \
which must be + initially empty, and an <dfn>animation frame callback \
identifier</dfn>, which is a number which + must initially be zero.</p>
+
+ <p>When the <dfn><code
+ data-x="dom-window-requestAnimationFrame">requestAnimationFrame()</code></dfn> \
method is called, + the user agent must run the following steps:</p>
+
+ <ol>
+
+ <li><p>Let <var>document</var> be <span data-x="concept-document-window">the
+ <code>Window</code> object's <code>Document</code> object</span>.</p></li>
+
+ <li><p>Increment <var>document</var>'s <span>animation frame callback \
identifier</span> by + one.</p></li>
+
+ <li><p>Append the method's argument to <var>document</var>'s <span>list of \
animation frame + callbacks</span>, associated with <var>document</var>'s \
<span>animation frame callback + identifier</span>'s current value.</p></li>
+
+ <li><p>Return <var>document</var>'s <span>animation frame callback \
identifier</span>'s current + value.</p></li>
+
+ </ol>
+
+ <p>When the <dfn><code

+ <li><p>Let <var>document</var> be <span data-x="concept-document-window">the
+ <code>Window</code> object's <code>Document</code> object</span>.</p></li>

the following + steps:</p>
+
