I think one of us is confused, but I think it's me. In any event, I can't find a way to add a sprite using pure mxml, but until someone shows us what we're missing, the actionscript is pretty easy:

<?xml version=" 1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        creationComplete="init()">
        <mx:Script>
                <![CDATA[
                        public function init():void {
                            var sprite:Sprite = new Sprite(); // replace "Sprite" (both places) with class you want to add

                            // drawing a rectangle on the sprite to prove adding the sprite worked in this example
                            sprite.graphics.beginFill(0);
                            sprite.graphics.drawRect(0,0,200,400);

                            holder.addChild(sprite); // add the sprite to any UIComponent
                        }
                ]]>
        </mx:Script>
        <mx:UIComponent id="holder" />
</mx:Application>

Additionally, intead of creating a Flex Project, you could create an Actionscript Project which I think uses Sprite as it's base class instead of Application.

Yes, Thanks Dan. I perfectly understand that Sprite class should
extend UIComponent class to get added in UIcomponent by AddChild
method. But its actually vice versa. But then How should try all
those samples which comes in Flex builder help and extends the class
sprite.
What I believe is if they have given example there should be some way
to use it also... How should I try all those code samples that is
given in flex builder help.
