Via this service, validatable control models inherit the ::com::sun::star::util::XCloneable interface.
If an validatable control model, at which a validator has been set (via XValidatable::setValidator), is being cloned, then the validator is also set at the clone. Effectively, this means that both control model instances share the same validator instance.

Setting an retrieving the current validator of the control model is possible via the XValidatable interface (which XValidatableFormComponent is derived from).

Easy access to the current value of the control, as well as it's validity (relative to the active validator), is provided by the methods XValidatableFormComponent::isValid and XValidatableFormComponent::getCurrentValue.

Note that the type of the value provided by XValidatableFormComponent::getCurrentValue is not specified here, but depends on the concrete control type.

As soon as a validator is set via XValidatable::setValidator, the validatable control model registers itself as listener. If the validity constraint of the validator changes, the ValidatableControlModel re-validates it's current valid, and broadcasts any resuling changes to all its XFormComponentValidityListener, if necessary.
