It seems to me that IBM are very keen to make it clear that this is NOT the case. They also typically state that DFDL would be the preferred option for new flows, but message sets remain a supported part of the product. |

Exactly my thoughts. Even more, I setup a VM with Broker 9 yesterday and deployed some message flows and message sets from V7.0.0.4 right into it and everything worked. Ok, so not an exhaustive test yet by they ain't going away.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

OK, time to state some facts:
- v8 will run any v7 message flow without modification. If it doesn't, it's a defect.
- The MRM domain and message sets remain a fully-supported part of the product. They are not deprecated and will be supported for many releases to come.
- IBM recommends that new message flows should use DFDL for parsing text and binary data - DFDL is better than MRM at most things.
Or, to put it more simply, DFDL is now the strategic technology and the MRM domain is de-emphasised in favour of DFDL. |

If you've got it working in DFDL why would you want to use a message set?

A DFDL is just an XML schema with some annotations.
You add a "sub complex type", whatever that is, by using the DFDL model editor to add a child element or add a complex type and then create an element of that type.
The exact same way you would do it in MRM. |

If the message is a bit complex, a lot complex or enough to make your brain leak out of your ears you still use DFDL.
I would put it to you that if the message is "too complex" for DFDL you've got no chance building a message set that will cope. There are DFDL schemas on GitHub for industry formats MRM can't manage (due to limited MRM bit level support)
