	//TODO: Check to see if Render really is overridden instead of a LiteralControl being added. It apears that this is the
	//case due to testing. Anything inside the block is overwritten by the content of this control, so it doesnt apear
	//to do anything with children.
	// a doc references this. add? protected override ControlCollection CreateControlCollection();
	
	//TODO: If Test.InnerText = Test.InnerHtml without ever assigning anything into InnerHtml, you get this:
