New Post: Using an XML Manifest

I am trying to figure out how to use an XML Manifest (e.g. contains 'paths' that can define the layout of menu items), kind of like the system in ICSharpCode.Core. I am not using ICSharpCode.Core due to the difficulty getting it to work with DevExpress controls.

Any ideas/suggestions/examples/etc? I may go to Mono.Addins, but I think making that work will be a real adventure.
