I am building a couple of XML based message sets that I would like to be validated. My message set contains Msg1, 2, and so on.
On then input node, I specify message set, format but leave the type blank and I turn on complete validation.
If I put in the message <Msg1></Msg1>, Broker validation automatically knows which message type I am putting in and attempts to validate the data against Msg1.
Although this is great but is this the intended behavior? Is this how validation works? If not then, how does it know against which message type to validate if I leave it blank? One answer that comes to mind is the mcd rfh2 folder but what about if that's blank too if message came from non rfh2 aware application.
Cheers.

MQInputNode properties are only DEFAULT, not required or overwrites.
If you put an XML message to a queue that has an MQInput node that is set to use the BLOB domain - and that message has a valid MQRFH2 that indicates that the message is in the XML Domain - then you will have InputRoot.XML, not InputRoot.BLOB.

Maybe I did not explain myself clearly so let me try again.
Input Node has Message Set: mrm:foo
Format: XML
Message Type: blank
Validation: complete
There are three different message types in the message set foo. How does validation routine know which message to validate data against?
Thanks a bunch.

The MQRFH2.
Or maybe it can match the root tag.

| Jeff is correct. When using MRM domain, the Message Type property is used to locate the correct message in the dictionary. For CWF and TDS, the Message Type is mandatory (ie, it must be given either in the RFH2 or on the node). For XML the Message Type is effectively optional, because the parser falls back to using the root tag as the Message Type. |
