schemas/VegCore/VegCore.ERD.mwb: specimen: added defining_data, which for a digital-only specimen, stores the information that comprises the specimen. note that a taxon_presence without a physical voucher can still qualify as reobservable if a detailed description of it is provided in this field, to make taxonomic redeterminations on. for datasources like VegBank, which incorrectly allow multiple taxon_determinations for any type of taxon_observation, their taxonomic redeterminations would actually be considered invalid if made on a purely taxon_presence observation (i.e. just a taxon name) without a detailed description that could be used to make a redetermination. this is different than the scrubbing of a taxon name, which relates a taxon name to another taxon name, rather than a taxon_observation to a completely different taxon name.
