> The conditional validation of dynamic properties in UpdateAttribute use the
> NON_EMPTY_STRING validator when state management is not enabled. This prevent
> the "Set empty string" checkbox option. The introduction of state management
> to this processor changed this behavior which previously allowed an empty
> string for an attribute value. The validator for the non-stateful case should
> be changed to return the original behavior.
