/**
 *  The SkinnableDataContainer class is the base class for all skinnable components that have 
 *  data content.
 *  While this container can hold visual items, it is often used only 
 *  to hold data items as children.
 *
 *  <p>The SkinnableDataContainer class takes as children visual components that implement 
 *  the IUIComponent interface and data items. 
 *  Data items can be simple date items such String and Number objects, 
 *  and more complicated data items such as Object and XMLNode objects. 
 *  While these containers can hold visual items, 
 *  they are often used only to hold data items as children.</p>
 *
 *  <p>An item renderer defines the visual representation of the 
 *  data item in the container. 
 *  The item renderer converts the data item into a format that can 
 *  be displayed by the container. 
 *  You must pass an item renderer to a SkinnableDataContainer container.</p>
 *
 *  <p>To improve performance and minimize application size, 
 *  you can use the DataGroup container. The DataGroup container cannot be skinned.</p>
