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