XML messages in the MRM and XML domains

If your messages are in XML, you can use either the XML Wire Format in the MRM domain, or one of the dedicated XML domains. Three XML domains are supported. The XMLNSC and XMLNS domains provide namespace support, but the XML domain does not support XML namespaces and is provided only for compatibility with WebSphere MQ Integrator Version 2.

Whether you choose the MRM domain, or one of the dedicated XML domains (XMLNSC or XMLNS), depends on the nature of your XML messages and the transformation logic that you want to use. The differentiating features of each domain are described below.

Tip: If you need to validate the content and values in XML messages, use the MRM domain.
Tip: If performance is critical, and you do not need to validate XML messages, use the XMLNSC domain.
Tip: If you need to preserve formatting in XML messages on output, use the XMLNSC domain with the option to retain mixed content.
Tip: If you are using XPath to access the message tree, and you require the message tree to conform as closely as possible to the XML data model, use the XMLNS domain.
Tip: If you are taking non-XML data that has been parsed by the CWF or TDS formats of the MRM domain, and transforming the data to the equivalent XML, use the MRM domain.
