If you want to apply the template to all the tabs in your page, you can use x:Type, but if you want to apply it to few tabs and not to all the tabs you can use x:Key.

Generally you will use x:Key when you want to use it as StaticResource in your xaml file. You will provide x:Name to a control or template when you want to refer it in your code-behind. I have never used X:Uid, but this is what MSDN says,

Use x:Uid to identify an object element in your XAML. Typically this object element is an instance of a control class or other element that is displayed in a UI. The relationship between the string you use in x:Uid and the strings you use in a resources file is that the resource file strings are the x:Uid followed by a dot (.) and then by the name of a specific property of the element that's being localized.
