    // Type names. We do reccomend that all uses of the validator bellow are converted to 
    // properties of type Type ( instead of string ) which use the TypeNameConverter from System.Configuration.dll

                // to the user so they know what exaclty is the problem ( i.e. the value must be a positive integer or be Infinite )
