About this task
You must create a message definition file before you can
create the message model objects. The message definition file contains
the logical and physical model definitions of the objects in XML Schema
form.
You can create the message definition file in one of the
following ways:
- Create the message definition file from scratch, see Message Sets: Creating a message definition file from scratch.
- Base your message definition file on an existing resource (for
example, an XML Schema file, an IBM® supplied
message, an XML DTD file, a C header file, a COBOL file, or a WSDL
file), see Message Sets: Creating a message definition file from an existing resource.
- Copy a message definition file from one message set
to another.
If you do copy a message definition file from one message
set to another, you must check that the source and target message
sets have identical physical formats, and that namespaces are enabled.
If
the source and target namespaces do not have identical formats, the
physical format of the message definition file might be replaced by
the default information applied to the target message set.
