- * The Repeating functionality is pretty tightly intermingled with other code,
- * so the process of pulling it out into this module will happen gradually.
- *
- * The current implementation adds a repeat form to the date field so the user
- * can select the repeat rules. That selection is built into an RRULE
- * which is stored in the zero position of the field values. During widget
- * validation, the rule is parsed to see what dates it will create,
- * and multiple values are added to the field, one for each repeat date.
- * That update only happens when the rule, the start date, or the end date
- * change, no need to waste processing cycles for other changes to the node
- * values.
- *
- * Lots of possible TODOs, the biggest one is figuring out the best
- * way to handle dates with no UNTIL date since we can't add an infinite
- * number of values to the field. For now, we require the UNTIL date.
