The following XAML (modified from the original version found in https://stackoverflow.com/a/11455413/1767995) cannot be loaded by NoesisGUI

    <Grid>
        <Grid.Resources>
            <RoutedUICommand x:Key="MyCommand1" Text="Text" />
            <RoutedUICommand x:Key="MyCommand2" Text="Another Text" />
        </Grid.Resources>

        <Grid.CommandBindings>
            <CommandBinding Command="{StaticResource MyCommand1}" 
                Executed="FirstMethod" />
            <CommandBinding Command="{StaticResource MyCommand2}" 
                Executed="SecondMethod" />
        </Grid.CommandBindings>

        <Grid.InputBindings>
            <KeyBinding Key="Z" Modifiers="Ctrl" Command="{StaticResource MyCommand1}" />
            <KeyBinding Key="H" Modifiers="Alt" Command="{StaticResource MyCommand2}" />
        </Grid.InputBindings>

        <StackPanel>
            <Button x:Name="btn1" Command="{StaticResource MyCommand1}" Content="Click me" />
            <Button x:Name="btn2" Command="{StaticResource MyCommand2}" Content="Click me" />
        </StackPanel>
    </Grid>

• RoutedUICommand class is not available to be used directly in the xaml.
• CommandBinding cannot use StaticResources to set the Command property.
