Yes, that is the purpose of this email. My understaning of the
process for changing the standard is that proposals are entered into the
Issue Tracker, followed by a 30 day period of public comment, followed by
the editor bringing the proposals to the executive for ratification. So,
technically, tdwg-content does not need to be notified prior to
ratification. (Is that correct?) Regardless, as much as I want to see our proposals ratified, I
don't want it to happen under the radar, and so thought it made sense to
inform the list.

I don't mind airing my positions on Issue 205, but would prefer not to
lead off with that. My questions and suggestions regarding the proposed
dwc:Organism class are not as important as our proposal to deprecate the
dwctype namespace, and to remove the phrase "The category of information
pertaining to" from the definitions of the dwc classes.
