Dialogs are ConditionTypes used by a Server to request user input. They are typically used when a Server has entered some state that requires intervention by a Client. For example, a Server monitoring a paper machine indicates that a roll of paper has been wound and is ready for inspection. The Server would activate a Dialog Condition indicating to the user that an inspection is required. Once the inspection has taken place the user responds by informing the Server of an accepted or unaccepted inspection allowing the process to continue.
