What is the meaning of x: name in xaml (WPF) and using it with a storyboard

Question

<Border Name="ItemBorder" Margin="5 5 0 5" BorderBrush="Black" BorderThickness="1" Height="75" Width="75">
  <Border.Background>
    <SolidColorBrush x:Name="ItemBorderBrush" Color="LightBlue"/>
  </Border.Background>
  <ContentPresenter/>
</Border>
<ControlTemplate.Triggers>
  <EventTrigger RoutedEvent="someEvent">
    <BeginStoryboard>
      <Storyboard TargetName="ItemBorderBrush" TargetProperty="Color" Duration="0:0:1" >
      <!--Storyboard TargetName="ItemBorder" TargetProperty="Background.Color" Duration="0:0:1"> -->
         <ColorAnimation To="White"/>
      </Storyboard>
    </BeginStoryboard>
  </EventTrigger>
</ControlTemplate.Triggers>

I will try to clearly explain my question. The name of the storyboard target when it is “ItemBorder” (comment line) works intermittently. Sometimes I get an error that the name "ItemBorder" could not be found in the area.

I decided to follow the style from the MSDN example of this and change the color property directly to the brush, instead of having the storyboard aim to be a border and change the color of the border brush by property (comment line). It seems to work.

However, it Name="ItemBorderBrush"does not compile because it is Namenot a property SolidColorBrush, so I use x:Name="ItemBorderBrush"both parameters Nameand x:Nameare accepted for the border. Why is this?

x: ( x:Name Name), Name ?
