Forcing the consumer to fill property

[×™×•× ×™ גולדברג]

Hi,
I have WS with WSDL file which describe some type, let's say an animalType.
I define in the code a "name" property to that type.
I want that property to be required, means that if the consumer of the
WS try to send animalType without specifiying the name,
an error will be raised.
Is it possible?

Thanks.
