Dave: I think I see what you're getting at... correct me if I'm wrong. So I decide that my aggregator is going to look for unknown Simple Extensions in Atom feeds and display them as a table of name/value pairs at the bottom of every entry. And during the display process, I'm going to run a regex over the values and linkify any URLs I find.
When someone's relative references just sit there as plain text and I get a complaint, who's to blame? (1) Me, for trying to provide generic support for unknown extensions? (2) The publisher, for failing to consider non-specific or limited support of the extension? (3) The complaining user, for expecting too much? If it's (3), then I agree with Tim... the spec says what it says, and that's fine. Otherwise, there may be a legitimate problem here. -- Roger Benningfield
