+<h2>Creating the YQL Plugin</h2>
+<h3>Plugin Constructor</h3>
+<p>To create a plugin, we need to create a constructor with a static
+ <code>NS</code> property. This is the namespace used by the plugin on each
+ instance.</p>
+
+<pre class="code prettyprint">// YQL plugin for Y.Tab instances
+var TabYQL = function(config) {
+ this.init(config);
+};
+
+TabYQL.NS = 'yql'; // plugin namespace (e.g. "tab.yql.load(myQuery)");</pre>
+
+
+</h3>Plugin Prototype</h3>
+<p>Next we will add the YQL functionality to the prototype. The init method
+ wires the YQL functionality up using the load method.</p>
+
+<pre class="code prettyprint">TabYQL.prototype = {
+ init: function(config) {
+ if (this.tab) {
+ this.tab.after('selectedChange', Y.bind(this.afterSelectedChange, this));
+ }
+ },
+
+ afterSelectedChange: function(e) {
+ // only load if not already loaded
+ if (!this.loaded) {
+ this.load(this.query, this.afterLoad);
+ }
+ },
+
+ load: function(query, afterLoad) {
+ Y.YQL(query, Y.bind(afterLoad, this));
+ }</pre>
+
+
+<h2>Creating the TabView</h2>
+<p>Next we will create a new instance of a TabView:</p>
+
+<pre class="code prettyprint">/* Create a new TabView instance, with content generated from script */
+var tabview = new Y.TabView();</pre>
+
+
+<p>And then use the <code>add</code> method to add the <code>Tab</code> instances,
+to add a tab for each of the feeds, then render the tabview into the placeholder
+element.</p>
+
+
+<pre class="code prettyprint">var feeds = {
+ Chrome: 'chrome+browser',
+ Firefox: 'firefox+browser',
+ Safari: 'safari+browser',
+ Explorer: 'explorer+browser',
+ Opera: 'opera+browser'
+};
+
+Y.each(feeds, function(feed, label) {
+ var tab = new Y.Tab({
+ label: label,
