Well, the values shown solely depends on your model. Just filter / sort it
accordingly? By default Tapestry adds all enum values to options (see
EnumSelectModel). Unfortunately you can not derive from EnumSelectModel, so I
would try to start from AbstractSelectModel copy and paste a few lines from
EnumSelectModel and provide a filter predicate which filters results in
"getOptions" according to your requirements (retrieve all, filter and return
the filtered list)
