To handle event catches,
you draw one or more routes from the event catch to another step
in the process diagram.
For example, to handle a situation where an operation fails and
normal processing cannot continue, you can draw a route from the
operation’s exception event catch to a Send With Document operation
that the Email service provides. The operation sends an informative
email to a system administrator to investigate the problem.
When you draw a route from an exception event catch, you specify
the exception that the event catch reacts to.
