>     INPUT
> | Serializes the value of each byte in the 4GL value according to the XML Schema serialization rules for the data type. If the mapping is to a base64Binary value with the encoding attribute set, the value is base-64 encoded and copied directly from the 4GL parameter without serialization.
>     OUTPUT
> | De-serializes the value of each byte in the 4GL value according to the XML Schema serialization rules for the data type. If the mapping is from a base64Binary value, it is always de-serialized into the 4GL parameter.
