Passing an enum value as command parameter when using MultiBinding

Question

I want to do something similar to this post but using MultipleBindings.

So something like this:

    <Button.CommandParameter>
        <MultiBinding Converter="{StaticResource commandParametersConverter}">
            <MultiBinding.Bindings>
                <Binding Path="DataContext" />
                <Binding Path="{x:Static vm:Direction.Down}" Mode="OneWay"/>
            </MultiBinding.Bindings>
        </MultiBinding>
    </Button.CommandParameter>

The line:

    <Binding Path="{x:Static vm:Direction.Down}" Mode="OneWay"/>

Throws error: Object reference not set to an instance of an object. I assume a static is not permitted in this context, so what's the next best option?

Change Path to Source in <Binding Path="{x:Static vm:Direction.Down}" Mode="OneWay"/>:

<Button.CommandParameter>
    <MultiBinding Converter="{StaticResource commandParametersConverter}">
        <MultiBinding.Bindings>
            <Binding Path="DataContext" />
            <Binding Source="{x:Static vm:Direction.Down}" Mode="OneWay"/>
        </MultiBinding.Bindings>
    </MultiBinding>
</Button.CommandParameter>
