Dear Sam, When you say: > but it seems impossible that different archetypes could share the > same data
am I right in recalling that a generic and re-usable part of a "data" tree has usually been defined as a CLUSTER archetype that is then referenced by several different archetypes? ... and, that an ENRY archetype could in theory contain only one referenced (pre-existing) CLUSTER as its sole data content, ... and, that CLUSTER archetypes can themselves be specialised if needed. Could you (or John) give an example of the additional requirement that is now requested?
