How do I assign list of values to property in xaml?

I've made a custom control that has a property of list type:

MyMenu.cs

[ContentProperty("MyMenuItems")]
public class MyMenu : View
{
    public List<MyMenuItem> MyMenuItems { get; set; }
}

And I want to assign list of values to the property like this:

MyPage.xaml

<local:MyMenu>
    <local:MyMenuItem />
    <local:MyMenuItem />
</local:MyMenu>

But it doesn't work neither with <x:Array> extension.
How can I pass to the property in xaml?
