   * this model thus far only supports finding an appropriate plugin dynamically, for a content item. How exactly the plugin then interoperates with Lenya is still open. My guess: depending on the purpose of the plugin (e.g. "for editing"), a more precise contract can be defined (e.g. such a plugin must be able to receive a piece of content, and have a callback registered for saving it)
   * what does a plugin implementation consist of ? Presumably each plugin will have a subdirectory, with sitemap, xsls, and configuration files. Depending on the plugin, it may also have Java classes etc. For individual XML editors, ideally no Java classes are required, as the {{{XMLEditorManagerPlugin}}} would be the service to access information about them.
