- GUID (Globally Unique ID) string to allow reference to a document
- Digital Signature for the document, and its authors
- List of places for the reader to find updates, comments, etc.
- List of places where the author publishes his comments, ratings, etc.
If this page, for example, were created in my desired future, there would be a link to a public comments server somewhere, to help with compatibility to the current web browsers.
A FireFox plugin would search the document and its locale (folder, server, etc) for a list of places to find and put comments, markup, etc. It might also search some private lists as well for comments hosted by communities I'm involved in.
The browser then could check through the identities of the authors of comments, and highlight or hide their comments based on various pools of reputation to which the reader has access.
It's a much richer, more complex, and if done properly, a closer approximation to the way we social humans deal with each other. We're still at Web 0.1, we're not even up the the level of the Vannevar Bush vision of the memex which at least allowed for markup of existing documents.
