I understand the proposal. I'm just pointing out that currently, the
distinction exists already in some other form—as noted, what you call
lesser elements is currently the set difference between greater elements
and elements. Therefore, it is hardly a huge step forward.

In any case, both proposals are incomplete.

For clarity, I mean three terms /in addition to "elements"/. For
example, a drawer, a paragraph and a planning line all are elements.
Yet, they may be different enough so as to deserve their own label.

Some objects can contain other objects. Others cannot. Per above, it may
be ambiguous to use the term "object" for both categories.

In a nutshell, naming is hard.
