Interop with *what*, Robert? What's the baseline? No aggregator *requires* a title... one can be synthesized. No aggregator *requires* an id... links, hashes, and so on do the job sufficiently for most purposes. No aggregator *requires* a date... if one's not attached, we can just slap on the date we acquired the entry. And so on... I honestly can't think of a single child of atom:entry that is required for interop. In which case, the only MUST in the spec would be "atom:entry MUST contain at least one child element of some kind. Have fun with that." No one needs Atom for producing a title-and-link feed. It's overkill, and pointless. The juice in Atom is in the handling of content... providing for explicit summaries, and clearly defined payload types. -- Roger Benningfield
