Considering I had to look up what DRY meant before replying to this
message, I may be missing your point. Is the repeat here that each
subclass has to define its own list of standard attributes? Or, is it
that the standard_attributes list holds strings, but I could build that
list up by looking at my existing attributes?
If you're feeling charitable, can you explain what you mean a little
more?
TIA
