Message Sets: XML Schema extensions in message sets
IBM® Integration Bus provides some additional facilities that are not specified in the XML Schema 1.0 specification. When using a message set, further extensions are provided.
Composition
The message model in a message set adds the following compositions that are beyond the XML Schema 1.0 specification:
Compositions orderedSet and unorderedSet enable message models that were produced in earlier versions of the product to be supported.
Content validation
The message model in a message set adds a validation control called ‘Content validation' that is used only if the domain is MRM or IDOC, and if validation is selected. It determines how strictly the content of the group is validated. See MRM content validation for more details.
The Content validation property does not affect validation in the XMLNSC or SOAP domains. Validation in these domains follows the rules of XML Schema 1.0.
Physical format information
If one or more physical formats are defined for a message set, the XML Schema objects within the message set can hold extra information about how they must be parsed and serialized.
