Existing Wording: UML indicates that cardinality of List in Section is 0..1

Proposed Wording: UML should indicate that cardinality of List in Section is 1..1

Comment:

List should be a required component of the Section class.

I can think of no reason to not require List in the Section class. The list supports emptyReason which would be used when a section contains no entries.

The List defined the attested narrative content of the Section and in turn the attested narrative content of the document. When a section is empty, it should use the List emptyReason to indicate the reason there is not content. There seems to be no reason to make it optional.
