This field lists the message set projects that are available in your workspace.
By clicking on the '+' symbol to the left of the project, these will expand
to list the message sets that are available for you to select. Depending on
how you started the New message definition file wizard,
a message set might be preselected for you. This does not prevent you from
selecting a different message set if you prefer.
File name
