Good Day,

WSDL Document Example uses complexTypes in its schema, such as -



In this specific case, it seems to me that an XSD simple element would suffice, such as -



Therefore, is there any reason for the usage of complexTypes here?

Regards,
Dan

You are right that in this particular case a single element could be enough.

However it is a known convention to have a common root to all inner elements. So even though with one element it is not really helpful, it is still used. It also makes the SOAP more readable as the wrapper element name is based on the method name.
