+ * @class Ext.DomHelper
+ * @alternateClassName Ext.core.DomHelper
+ *
+ * <p>The DomHelper class provides a layer of abstraction from DOM and transparently supports creating
+ * elements via DOM or using HTML fragments. It also has the ability to create HTML fragment templates
+ * from your DOM building code.</p>
+ *
+ * <p><b><u>DomHelper element specification object</u></b></p>
+ * <p>A specification object is used when creating elements. Attributes of this object
+ * are assumed to be element attributes, except for 4 special attributes:
+ * <div class="mdetail-params"><ul>
+ * <li><b><tt>tag</tt></b> : <div class="sub-desc">The tag name of the element</div></li>
+ * <li><b><tt>children</tt></b> : or <tt>cn</tt><div class="sub-desc">An array of the
+ * same kind of element definition objects to be created and appended. These can be nested
+ * as deep as you want.</div></li>
+ * <li><b><tt>cls</tt></b> : <div class="sub-desc">The class attribute of the element.
+ * This will end up being either the "class" attribute on a HTML fragment or className
+ * for a DOM node, depending on whether DomHelper is using fragments or DOM.</div></li>
+ * <li><b><tt>html</tt></b> : <div class="sub-desc">The innerHTML for the element</div></li>
+ * </ul></div></p>
+ * <p><b>NOTE:</b> For other arbitrary attributes, the value will currently <b>not</b> be automatically
+ * HTML-escaped prior to building the element's HTML string. This means that if your attribute value
+ * contains special characters that would not normally be allowed in a double-quoted attribute value,
+ * you <b>must</b> manually HTML-encode it beforehand (see {@link Ext.String#htmlEncode}) or risk
+ * malformed HTML being created. This behavior may change in a future release.</p>
+ *
+ * <p><b><u>Insertion methods</u></b></p>
+ * <p>Commonly used insertion methods:
+ * <div class="mdetail-params"><ul>
+ * <li><tt>{@link #append}</tt> : <div class="sub-desc"></div></li>
+ * <li><tt>{@link #insertBefore}</tt> : <div class="sub-desc"></div></li>
+ * <li><tt>{@link #insertAfter}</tt> : <div class="sub-desc"></div></li>
+ * <li><tt>{@link #overwrite}</tt> : <div class="sub-desc"></div></li>
+ * <li><tt>{@link #createTemplate}</tt> : <div class="sub-desc"></div></li>
+ * <li><tt>{@link #insertHtml}</tt> : <div class="sub-desc"></div></li>
+ * </ul></div></p>
+ *
+ * <p><b><u>Example</u></b></p>
+ * <p>This is an example, where an unordered list with 3 children items is appended to an existing
+ * element with id <tt>'my-div'</tt>:<br>
+ <pre><code>
+var dh = Ext.DomHelper; // create shorthand alias
+// specification object
+var spec = {
+    id: 'my-ul',
+    tag: 'ul',
+    cls: 'my-list',
+    // append children after creating
+    children: [     // may also specify 'cn' instead of 'children'
+        {tag: 'li', id: 'item0', html: 'List Item 0'},
+        {tag: 'li', id: 'item1', html: 'List Item 1'},
+        {tag: 'li', id: 'item2', html: 'List Item 2'}
+    ]
+};
+var list = dh.append(
+    'my-div', // the context element 'my-div' can either be the id or the actual node
+    spec      // the specification object
+);
+ </code></pre></p>
+ * <p>Element creation specification parameters in this class may also be passed as an Array of
+ * specification objects. This can be used to insert multiple sibling nodes into an existing
+ * container very efficiently. For example, to add more list items to the example above:<pre><code>
+dh.append('my-ul', [
+    {tag: 'li', id: 'item3', html: 'List Item 3'},
+    {tag: 'li', id: 'item4', html: 'List Item 4'}
+]);
+ * </code></pre></p>
+ *
+ * <p><b><u>Templating</u></b></p>
+ * <p>The real power is in the built-in templating. Instead of creating or appending any elements,
+ * <tt>{@link #createTemplate}</tt> returns a Template object which can be used over and over to
+ * insert new elements. Revisiting the example above, we could utilize templating this time:
+ * <pre><code>
+// create the node
+var list = dh.append('my-div', {tag: 'ul', cls: 'my-list'});
+// get template
+var tpl = dh.createTemplate({tag: 'li', id: 'item{0}', html: 'List Item {0}'});
+
+for(var i = 0; i < 5, i++){
+    tpl.append(list, [i]); // use template to append to the actual node
+}
+ * </code></pre></p>
+ * <p>An example using a template:<pre><code>
+var html = '<a id="{0}" href="{1}" class="nav">{2}</a>';
+
+var tpl = new Ext.DomHelper.createTemplate(html);
+tpl.append('blog-roll', ['link1', 'http://www.edspencer.net/', "Ed&#39;s Site"]);
+tpl.append('blog-roll', ['link2', 'http://www.dustindiaz.com/', "Dustin&#39;s Site"]);
+ * </code></pre></p>
+ *
+ * <p>The same example using named parameters:<pre><code>
+var html = '<a id="{id}" href="{url}" class="nav">{text}</a>';
+
+var tpl = new Ext.DomHelper.createTemplate(html);
+tpl.append('blog-roll', {
+    id: 'link1',
+    url: 'http://www.edspencer.net/',
+    text: "Ed&#39;s Site"
+});
+tpl.append('blog-roll', {
+    id: 'link2',
+    url: 'http://www.dustindiaz.com/',
+    text: "Dustin&#39;s Site"
+});
+ * </code></pre></p>
+ *
+ * <p><b><u>Compiling Templates</u></b></p>
+ * <p>Templates are applied using regular expressions. The performance is great, but if
+ * you are adding a bunch of DOM elements using the same template, you can increase
+ * performance even further by {@link Ext.Template#compile "compiling"} the template.
+ * The way "{@link Ext.Template#compile compile()}" works is the template is parsed and
+ * broken up at the different variable points and a dynamic function is created and eval'ed.
+ * The generated function performs string concatenation of these parts and the passed
+ * variables instead of using regular expressions.
+ * <pre><code>
+var html = '<a id="{id}" href="{url}" class="nav">{text}</a>';
+
+var tpl = new Ext.DomHelper.createTemplate(html);
+tpl.compile();
+
+//... use template like normal
+ * </code></pre></p>
+ *
+ * <p><b><u>Performance Boost</u></b></p>
+ * <p>DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead

+ * <p>Element creation specification parameters may also be strings. If {@link #useDom} is <tt>false</tt>,

- * @class Ext.DomHelper
- * The DomHelper class provides a layer of abstraction from DOM and transparently supports creating
- * elements via DOM or using HTML fragments. It also has the ability to create HTML fragment templates
- * from your DOM building code.
- *
- * DomHelper element specification object
- * A specification object is used when creating elements. Attributes of this object
- * are assumed to be element attributes, except for 4 special attributes:
- * 

- * tag : The tag name of the element
- * children : or cnAn array of the
- * same kind of element definition objects to be created and appended. These can be nested
- * as deep as you want.
- * cls : The class attribute of the element.
- * This will end up being either the "class" attribute on a HTML fragment or className
- * for a DOM node, depending on whether DomHelper is using fragments or DOM.
- * html : The innerHTML for the element
- * 

- *
- * Insertion methods
- * Commonly used insertion methods:
- * 

- * {@link #append} : 
- * {@link #insertBefore} : 
- * {@link #insertAfter} : 
- * {@link #overwrite} : 
- * {@link #createTemplate} : 
- * {@link #insertHtml} : 
- * 

- *
- * Example
- * This is an example, where an unordered list with 3 children items is appended to an existing
- * element with id 'my-div':

- 

-var dh = Ext.DomHelper; // create shorthand alias
-// specification object
-var spec = {
-    id: 'my-ul',
-    tag: 'ul',
-    cls: 'my-list',
-    // append children after creating
-    children: [     // may also specify 'cn' instead of 'children'
-        {tag: 'li', id: 'item0', html: 'List Item 0'},
-        {tag: 'li', id: 'item1', html: 'List Item 1'},
-        {tag: 'li', id: 'item2', html: 'List Item 2'}
-    ]
-};
-var list = dh.append(
-    'my-div', // the context element 'my-div' can either be the id or the actual node
-    spec      // the specification object
-);
- 

- * Element creation specification parameters in this class may also be passed as an Array of
- * specification objects. This can be used to insert multiple sibling nodes into an existing
- * container very efficiently. For example, to add more list items to the example above:

-dh.append('my-ul', [
-    {tag: 'li', id: 'item3', html: 'List Item 3'},
-    {tag: 'li', id: 'item4', html: 'List Item 4'}
-]);
- * 

- *
- * Templating
- * The real power is in the built-in templating. Instead of creating or appending any elements,
- * {@link #createTemplate} returns a Template object which can be used over and over to
- * insert new elements. Revisiting the example above, we could utilize templating this time:
- * 

-// create the node
-var list = dh.append('my-div', {tag: 'ul', cls: 'my-list'});
-// get template
-var tpl = dh.createTemplate({tag: 'li', id: 'item{0}', html: 'List Item {0}'});
-
-for(var i = 0; i < 5, i++){
-    tpl.append(list, [i]); // use template to append to the actual node
-}
- * 

- * An example using a template:

-var html = '{2}';
-
-var tpl = new Ext.DomHelper.createTemplate(html);
-tpl.append('blog-roll', ['link1', 'http://www.jackslocum.com/', "Jack's Site"]);
-tpl.append('blog-roll', ['link2', 'http://www.dustindiaz.com/', "Dustin's Site"]);
- * 

- *
- * The same example using named parameters:

-var html = '{text}';
-
-var tpl = new Ext.DomHelper.createTemplate(html);
-tpl.append('blog-roll', {
-    id: 'link1',
-    url: 'http://www.jackslocum.com/',
-    text: "Jack's Site"
-});
-tpl.append('blog-roll', {
-    id: 'link2',
-    url: 'http://www.dustindiaz.com/',
-    text: "Dustin's Site"
-});
- * 

- *
- * Compiling Templates
- * Templates are applied using regular expressions. The performance is great, but if
- * you are adding a bunch of DOM elements using the same template, you can increase
- * performance even further by {@link Ext.Template#compile "compiling"} the template.
- * The way "{@link Ext.Template#compile compile()}" works is the template is parsed and
- * broken up at the different variable points and a dynamic function is created and eval'ed.
- * The generated function performs string concatenation of these parts and the passed
- * variables instead of using regular expressions.
- * 

-var html = '{text}';
-
-var tpl = new Ext.DomHelper.createTemplate(html);
-tpl.compile();
-
-//... use template like normal
- * 

- *
- * Performance Boost
- * DomHelper will transparently create HTML fragments when it can. Using HTML fragments instead
- * of DOM can significantly boost performance.
- * Element creation specification parameters may also be strings. If {@link #useDom} is false,
- * then the string is used as innerHTML. If {@link #useDom} is true, a string specification
- * results in the creation of a text node. Usage:
- * 
-Ext.DomHelper.useDom = true; // force it to use DOM; reduces performance
- * 
- * @singleton
