Namespace documentation on a .Net project (Sandcastle)?

Question

I started using Sandcastle some time ago to generate a Documentation Website for one of our projects. It's working quite well but we've always only written documentation for classes, methods, properties (...) in our project and had completely separate documentation for the overall project and project parts/modules/namespaces. It would be nice if I could merge that documentation together and add respective documentation to the generated helper files but I can't figure out how to do it.

Just adding comments to the namespace declaration doesn't seem to work (C#):

/// <summary>
/// My short namespace description
/// </summary>
namespace MyNamespace { ... }

Does anyone know how to do this? I know it's possible somehow and it would be really nice to have... :)

Sandcastle also supports the ndoc-style namespace documentation, which allows you to stick the documentation in the source files:

Simply create a non-public class called NamespaceDoc in the namespace you want to document, and the xml doc comment for that class will be used for the namespace.

Adorn it with a [CompilerGenerated] attribute to prevent the class itself from showing up in the documentation.

Example:

namespace Some.Test
{
    /// <summary>
    /// The <see cref="Some.Test"/> namespace contains classes for ....
    /// </summary>

    [System.Runtime.CompilerServices.CompilerGenerated]
    class NamespaceDoc
    {
    }
}
