I think the 3rd name Rich is referring to might be the title given to each Dynamic Component/Group attribute block in the Dynamic Component Attributes window? Revisions to these titles can be tricky to manage, depending on whether a user wants parity between these titles and other names/definitions. Mainly because the titles aren't automatically updates when a user changes the name in Entity Info (as happens with the Outliner). Things get even messier depending on whether folks use generic "Parent![Attribute]" references when passing parent attributes down to nested components/groups, or whether they use more specific "Boxes![Attribute]" references. Haven't seen very many cases where folks create Dynamic Groups, but it's possible, so... fwiw.
