• In/Out: This direction means that the argument can be used within and outside the given workflow.An IN/OUT type of argument is used when you want to send a variable as parameter and want the modified value of the same variable as return value. Naming Convention should be: io_<Argument Name>(Ex: io_Name)
• Property: This direction is not in use currently.
