Constraints Applied to Variables

Service Development Help : Properties : Variable Properties : Constraints Applied to Variables

Designer displays small symbols next to a variable icon to indicate the constraints applied to the variable. Designer displays variables in the following ways:

Variable	Constraint status	Variable Properties
	Required field.	The Required property is set to True.
	Optional field.	The Required property is set to False.
	Required field with content type constraint	The Content type property specifies an IS schema or XML schema.
	Optional field with content type constraint	The Required property is set to False and the Content type property specifies an IS schema or XML schema.

Note:

Designer displays the ‡ symbol next to String, String list, and String table variables with a content type constraint only. Designer does not display the ‡ symbol next to Object and Object list variables with a specified Java class constraint. Object and Object lists with an applied Java class constraint have a unique icon. For more information about icons for constrained Objects, see Java Classes for Objects.
