There may not be any practical use of what I want to do, but just to satisfy my curiosity can we compact the 2nd binding in the following XAML into 1 line
<TextBlock>
<TextBlock.Text>
<MultiBinding Converter="{StaticResource MyConverter}">
<Binding Source="{StaticResource One}"></Binding>
<Binding>
<Binding.Source>
<sys:String>2</sys:String>
</Binding.Source>
</Binding>
</MultiBinding>
</TextBlock.Text>
</TextBlock>
StaticResource One gives me "1" and MyConverter just concatenates all values it gets. What I am looking for is some way to express the 2nd binding in a compact format like the 1st binding.
