-// GetOkExists returns the data for a given key and whether or not the key

+// GetOkExists can check if TypeBool attributes that are Optional with

 //
-// This is nearly the same function as GetOk, yet it does not check

-// without a default, to fully check for a literal assignment, regardless
-// of the zero-value for that type.
-// This should only be used if absolutely required/needed.
