Using plain SQLite one can use alter table to add/remove table
columns after the table has been created.
In the same (or not the same) way, is it somehow possible to
dynamically add attributes to an entity? This would, among other
things, involve that when a new attribute is added, all existing MOs
(and their persistent counterparts; what are they called again?)
will now respond properly to that new attribute. And when an
attribute is removed, it gets gracefully deleted from all MOs (and
their persistent counterparts; am I even using the correct words
over here? I hope you get my point).
