There seems to be a lot of opinions about what RSS's purpose is. In order for the syntax to be effectively defined, this purpose needs to be clearly established and stated on the main page.
Feed : Use for computer-friendly syndication (similar to CDF in functionality)
Editing : Use between RSS-enabled clients and servers to create and update entries, comments, and either annotate or edit other resources (MetaWeblog)
Archiving : Use for internal storage, import, and export of entries, comments, and other resources (here)
Commenting : Use to post comments to an entry (CommentApi)
Cross-linking : Use to notify one entry about another entry (usually external, similar to TrackBack)
