Alter the definition of atom:updated.
The definition of atom:updated is confusing, and causes rational people to disagree on its purpose.
The phrase "bring to the attention of subscribers" is inadequate, as it depends entirely on the definition of terms. Undefined terms:
* "Subscribers" (we use "producer", "consumer", and "processor"... this is a new one)
Replace the first paragraph of the current definitions of atom:updated with the following:
The "atom:updated" element is a Date construct indicating the most recent instant in time when the [feed/entry] was modified in a way the producer considers significant. Ergo, not all modifications necessarily result in a changed atom:updated value.
