Message model objects: Wildcard elements
For XML messages, a wildcard element represents an element that is not present in the message model, but which might be present at the position of the wildcard element in a message.
Wildcard elements provide a means of adding flexibility to the message model, so that messages can be parsed even if they do not exactly match the message model.
Wildcard elements can be present only within a complex type or group with Composition of sequence.
The Process Content and Namespace properties control the namespace to which elements that are present at the position of the wildcard element must belong.
