    <p>There are two methods how the value which is represented by a control model
    can interact with other components (well, except the trivial ones accessible
    by using com::sun::star::beans::XPropertySet):
    <ul><li>binding the value to an external component via com::sun::star::form::binding::XBindableValue</li>
        <li>validating the current value by an external component, via XValidatable and XValidator</li>
    </ul></p>

    <p>The ValidatableBindableControlModel services describes the interaction of these concepts
    for control models which support both of them.</p>

        established as validator, as if it has been passed to XValidatable::setValidator().<br/>
