It would probably be better if the regex allowed 1-, 2- and 3- part version ids at the end, even though they will never turn up in ADL 1.4 slot filling statements. The reason is that if we do this, the slot refs don’t have to be reprocessed to allow them during conversion to ADL2 archetypes, where such refs can be used.
It’s also not really correct to have such restrictive regexes in slot references, since if we decided to change what chars were legal in archetype ids, all slot refs would become invalid. They should instead be permissive, e.g. something like:
allow_archetype CLUSTER[at0002] occurrences matches {0..*} matches { -- CLUSTER_SLOT
include archetype_id/value matches {/openEHR-EHR-CLUSTER\.device(-[^.]+)*\.v.+/}
}
on the assumption that only valid archetype ids will validate in template slot-filling statements anyway.
