asp.net mvc - MvcSiteMap: Dynamic node provider not reached

Question

I created a project that the nodes are defined using attributes, and I set it in the web.config to scan for attributes, and it works fine.
I don't use an XML file at all.

Now I want to add a dynamic node provider, how do I do it?
Is there a way to do it without the XML (.sitemap) file?
I need to make sure it's under the root, which has been set in code using MvcSiteMapNodeAttribute attribute.

I've read the documentation and I can't really figure out where to place this line:

<mvcSiteMapNode
  title="Details" action="Details"              
  dynamicNodeProvider="Project.StoreDetailsDynamicNodeProvider, Prject" />

What action is it supposed to point to? Additionally as said above, the root element is defined using attributes, so my question is if there is a way to avoid XML, or alternatively what's the efficient way to declare the XML (the less the better) to include my dynamic provider.

Update

I've tried the following and the node provider still isn't reached (From HomeController.cs).

[MvcSiteMapNode(Title = "Home", Key = HomeMenuKey,
  DynamicNodeProvider = "Project.Namespace.NodeProvider, Assembly")]
public ActionResult Index()
{
  return View();
}

Answer 1

Can you define it in the controller method attributes (and not use XML at all)?

For example:

[MvcSiteMapNode(Title="Details", 
  DynamicNodeProvider = "Project.StoreDetailsDynamicNodeProvider, Project")]
public ActionResult Index()
{
    return View();
}
