wpf - Use IValueConverter with DynamicResource?

Question

Is there a way to define a converter when using the DynamicResource extension? Something in the lines of

<RowDefinition Height="{Binding Source={DynamicResource someHeight}, Converter={StaticResource gridLengthConverter}}" />

which unfortunately gives me the following excpetion:

A 'DynamicResourceExtension' cannot be set on the 'Source' property of type 'Binding'. A 'DynamicResourceExtension' can only be set on a DependencyProperty of a DependencyObject.

I know i am really late to this but what definitely works is using a BindingProxy for the DynamicResource like this

<my:BindingProxy x:Key="someHeightProxy" Data="{DynamicResource someHeight}" />

Then applying the converter to the proxy

<RowDefinition Height="{Binding Source={StaticResource someHeightProxy}, Path=Data, Converter={StaticResource gridLengthConverter}}" />
