    Expression="{Binding Path=ModelItem.SampleValue,   
                         Mode=TwoWay,   
                         Converter={StaticResource ArgumentToExpressionConverter},   
                         ConverterParameter=In }"  
    ExpressionType="s:String"  
    OwnerActivity="{Binding Path=ModelItem}"
