Size Is Processing
The sizeIs attribute may be used to determine or control the size of an element when deserialization and serialization occurs. On deserialization, SOAPam Server will automatically calculate a value for the 'sizeIs' element based on the size, in bytes, of the subject element in the request. On serialization, SOAPam Server expects the sizeIs element to have been set correctly by the server. It serializes to the response only the number of bytes indicated by the sizeIs element.
