The general structure of the classification scheme
Large classes (groups of types):
1.Eruptive variable stars
2.Pulsating variable stars
3.Rotating variable stars
4.Cataclysmic (explosive and nova-like) variables
5.Close binary eclipsing systems
6.Optically variable close-binary sources of strong variable X-ray radiation
7.
These classes are just a  way to group types; in our opinion, they can be kept if slightly better described (e.g., remove close from item 5, simplify item 6)
