Problem with get outer instance from xbl component

I am making my own component and within it I want to set value of outer instance. For example, my main form has:

<xf:model id="fr-form-model">                                                                                   
        <xf:instance id="fr-form-instance">                   
            <form>                                       
                <section-1>     
                    <myControl/>                                     
                </section-1>                               
            </form>                       
        </xf:instance>   
        ....
and inside myControl.xbl I have:

<xf:setvalue model="fr-form-model" ref="instance('fr-form-instance')/form/section-1/myControl" value="'myValue'" /> 
but unfortunately it doesn't see 'fr-form-model' (Reference to non-existing model id: fr-form-model) which is understandable, because component doesn't have to see outer elements, so how can I refer to outer instance ?

Do you want to write to the node the component is bound to?

If so, you can write to the control binding with xxf:binding():

Otherwise, the quick and dirty way is to use the xxf:instance() function instead. It has visibility through the boundaries of XBL components. But we don't recommend it as it breaks encapsulation.

Thank You very much for response. I used xxf:instance() and it worked excellent.
