[tdwg-content] Name is species concept thinking

Well, for starters, zoobank is not in the business of dealing with taxon
concepts -- so I wouldn't use that domain name in the example.

Also, what *is* the correct pl;ace to get DwC?  Peter was using
http://code.google.com/p/darwincore/wiki/Taxon; but I've been using
http://rs.tdwg.org/dwc/index.htm.  Now I'm thoroughly confused....
