Archetypes vs. Templates, archetype version in slots

Hi,

While reviewing CKM archetypes we found that slots are usually
pointing to other v1 archetypes.
Shouldn't archetype slots point to any version of the included
archetypes and not a single archetype? Shouldn't be Templates the ones
pointing to an specific archetype?

This is also true even for "archetype and all its children" slots
(e.g. openEHR-EHR-OBSERVATION\.
respiration(-[a-zA-Z0-9_]+)*\.v1) in
which the v1 seems to be even more misplaced as it points to a set of
archetype v1 by default.

Probably v1 should be changed to v[0-9]+ (or even v[0-9\.]+)

Regards
