I wholefully agree there: let's define first a conceptual model, then we
should discuss of its implementation.

However, we must agree on model extend: will it concerns only concept
description (aka: characters) or also case description (aka: items) ? IMHO,
only the first one can be generalized, or we'll have to validate the case
description twice: against a generic model and against its concept.

For using an exemple, if i have a description of the characters of
Pociloporidae familiy, and a description of the items of Pociloporidae
family, i'll have to make sure characters are really characters (validating
against generic character model), to make sure items are really items
(validating against generic items model), and make sure Pociloporidae items
are really Pociloporida (validating items against characters). I would prefer
to have only to validate characters againt a generic character model, and
validate items against characters, meaning using a character description as a
suitable model for items description.
