// Description: 
//              This is a helper struct to facilate the storage of Security critical data ( aka "Plutonium") 
//              It's primary purpose is to do put a [SecurityCritical] on all access to the data.
// 
//              What is "critical data" ? This is any data created that required an Assert for it's creation.
//              As an example - the creation of an HwndWrapper during Dispatcher.Attach.
//              The current implementation requires the consumer to use the data member only if IsValid is true
// 
// History:
//  10/25/05 : akaza Created.
