This is a > requirement on the feed publisher. -1, sorry, can't agree with this The "atom:updated" element is a Date construct indicating the most recent instant in time when an entry or feed was modified in a way the publisher considers significant. Therefore, not all modifications necessarily result in a changed atom:updated value. atomUpdated = element atom:updated { atomDateConstruct } Publishers MAY change the value of this element over time. A minor and trivial change to a linked resource, eg. whitespace, could well cause a change in (eg.) the hash, but that (usually) is not significant. Similarly a change in the 'accessed' attribute especially when the 'hash' and 'etag' *didn't* change is pretty much the definition of not-significant. s/MUST/MAY/ e.
