(Richard Grevers lists@dramatic.co.nz):
I suggest that we look at some way of introducing classes based on the semantics of the data. For example, a wiki-method of entering <span class="species"> - although if we go that far we may as well look at an xml-based wiki (<species>) using server-side XSLT with a range of standard and personal-choice stylesheets.
Did you read the proposal? I suggest doing exactly that with a very simple syntax. Re-read it:
