Question: Workaround like Interaction.Behaviors for custom attached properties

[HavenDV]

I'm trying to work around a problem like this: The object 'Label' already has a child and cannot add ''. 'Label' can only accept one child.

<Label Grid.Column="1"
       Grid.Row="1">
    <ui:Helper.Text>
        <PriorityBinding>
            <Binding Path="Worker.Employer.Name" StringFormat="Employer: {0}" />
            <Binding Source="Unemployed" />
        </PriorityBinding>
    </ui:Helper.Text>
    <Binding RelativeSource="{RelativeSource Self}" Path="(ui:Helper.Text)" />
</Label>

SO: https://stackoverflow.com/questions/17179746/the-object-label-already-has-a-child-and-cannot-add-label-can-accept-onl

I see that Interaction.Behaviors gets around this limitation but couldn't replicate this using the approach from https://github.com/microsoft/XamlBehaviorsWpf/blob/master/src/Microsoft.Xaml.Behaviors/Interaction.cs What else is required besides this approach for this to work?
