Gets or sets the name of an Arcade expression that returns a boolean value. When this expression evaluates to 'true' and the element is visible, the element must have a valid value in order for the feature to be created or edited. When the expression evaluates to 'false' the element is not required. If no expression is provided, the default behavior is that the element is not required. If the referenced field is non-nullable, the required expression is ignored and the element is always required.
