Originally, the definition of applied schema ("character definitions", lexica, terminology) is outside the scope of this discussion group. While judging from my own experience I think it unlikely to make fast progress here, I completely agree that it is most important to work on it. I would therefore endorse Alex's proposal to create a new top level subject: -> Please do use a subject line (LEX) if you want to talk about applied terminology for a certain group (all plants, all insects, etc.) If these discussion threads become too big, we should then open a new list for those interested in it.
