The mq.mtt type tree has definitions for: 
♦  MQSeries Header MessageDescriptor 
The MessageDescriptor Header type defines the components and format of the 
message descriptor. (Use this for OS/390 Batch, OS/390 CICS, or IBM 
WebSphere MQ 2.x). 
♦  MQSeries Header MessageDescriptor2 
The MessageDescriptor2 Header type defines the components and format of 
the message descriptor for IBM WebSphere MQ 5.x. 
♦  MQSeries Header MQSLink4R3 
The MQSLink4R3 Header type defines the components and format of the IBM 
WebSphere MQ Link for R/3 Header. When the IBM WebSphere MQ Link for R/3 
is used for source data, the input message data always contains a header; 
however, you must create the header for an output message. The MQSeries 
Link for R/3 Header is not optional. It always appears in your input data and it 
must be included when mapping output data. 
Use one of these types for 
the type of an input or 
output card. 
Add a message content type as 
a component of MessageData.
