As an information scientists and not a "taxonomists" in the systematics use of
the world, but certainly a taxonomists in the Library Science use of the word,
e.g. Dewey Decimal Classification (DDC) I think the work practice now is to
describe higher level taxonomic concepts independent of the raw data the
specimen. It is the description of a class of objects not the object
themselves. Even at the species level the taxonomists is not claiming to have
seen all of the individuals, just enough to make generalizations. So I think
this generalization needs to be addressed by SDD. It would be icing on the
cake if SDD could deal with the relationship to instance data as well.
