Messages consist of one or more logical parts. Each part is associated with a type from a type system using a message-typing attribute. The set of message-typing attributes is extensible.
WSDL defines several such message-typing attributes for use with XSD:
- element: an XSD element using a QName.
- type: an XSD simpleType or complexType using a QName.
Other message-typing attributes may be defined as long as they use a namespace different from that of WSDL. Binding extensibility elements may also use message-typing attributes.
