Can you explain in more detail why they should be fundamentally different?
Aren't the differences just a matter a matter of degree, different points
on a continuum of data as it were? And aren't the basic principles
applicable across the whole?
Is not the issue we are dealing with here one of how to deal with
biological descriptive information whether at the level of individual
components of the specimen (e.g. each of the leaves), the specimen as a
whole (e.g. the variation of leaves on a specimen) or the taxon (e.g. the
variation of leaves across all specimens of the species, or the higher
level taxon)? Or at any other level, or mixture of levels, we might chose?
Is it not possible, and indeed preferrable, to have a single scheme that
covers all of these situations?
I am finding it a bit difficult to get a grip of this discussion and where
it is going (or where it is coming from, for that matter). I thought I
understood (and agree with) your previous post about the need for a
definition component as distinct from the the description and data in the
same manner as the DTDs of SGML, but I am now not so sure if that is what,
or all of what, is being suggested.
