This page is meant to capture those elements for the PUI that are not able to be reflected in a wireframe, but will make a big difference in the experience.
Inheritance:
When data is not entered into a record, the record should inherit the data from the record that is the next level up from it that has data entered. E.g. if an item's parent has data, then the record inherits that. If the item's parent does not have data, then it inherits from the grandparent (and so on).
Note that further discussion is needed by the WG as to whether or not this is true for all fields. Tagging Mark Custer to evaluate this.
