feature request #8128
Add indicator for feature facts and/or vocabularies which description type they support
we need to distinguish if features and/or their vocabularies support taxon facts, specimen facts and/or name facts.
Discuss: is it possible that features support >1 of these 3? Also consider that structured descirptions are handled in Characters now.
