//LAMESPEC: The dox talk about HttpException but are very ambigious.
//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:
// Exception Details: System.Web.HttpException: Cannot get inner content of Message because the contents are not literal.
