      Allowed values are "action", "actionListener", "actionFromValue", "isNotSet", "isSet", "valueIfSet".
      "action" (method binding) evaluate the expression to find the method binding which is referenced with the template.
      "actionListener" same as "action" but for the method signature of ActionListeners.
      "isSet" (boolean) checks, if the expression is set from the composition caller.
      "isNotSet" (boolean) negation of "isSet"
      "actionFromValue" Evaluates the ValueBinding to get an outcome set directly (no action method)
      "valueIfSet" set the attribute only if the value is set.
