Kevin Lynch: These XML blog feeds come in several different formats today (RSS 0.91, 0.92, 1.0, 2.0) which don't appear to have provisions for embedded comments. Atom is another emerging format for these feeds, and is currently under development by a number of blog software creators. This is an opportunity for us to agree on how both entries and comments can appear in our blog readers. Here are some thoughts on this, building on the ideas on the Atom site.

I've prototyped the first approach here.  Note the addition of a <related> element.  Should entries which are a result of a trackback have two related elements?
