This boolean expression is used to determine if this action will execute. Use it to enable or disable actions programatically. For example, you'd enable a ShowError action only if you've found an error let's say when you parsed a response from a web service. A common example is [HasRole:Administrators|true] (which requires My Token to work) or [SomeField] == "Some Value". This field supports Tokens.
