    // In a semi-arbitrary way, we have decided to make abstract classes into
    // "groups" and concrete classes into "complexTypes".
    //
    // This is because about the only thing you can do with an abstract
    // class (err. node) is inherit from it with a "concrete" element. Therefore,
    // in this manner, we need a group node for abstract classes to lay out the child
    // element choices so that the child, concrete class may be plugged into whatever spot
    // it parent could go. The tradeoff is that "group" nodes may not be extended, so the
    // choices that you lay out here are it (e.g. no more nodes may inherit" from this group)
    //
    // The flipside for concrete classes is that we want to use them as elements in our document.
    // Unfortunately, about all you can do with complexTypes in terms of inheritance, is to
    // use these as the basis for a new node type. This is NOT full inheritence because the new
    // class (err. element node) wont be able to go into the document where it parent went without
    // you heavily editing the schema.
    //
    // Therefore, IF a group is abstract, but has no inheriting sub-classes, there are no choices, and its nigh
    // on pointless to declare it as a group, in this special case, abstract classes get declared
    // as complexTypes.
    //
    // Of course, in OO methodology, you should be able to inherit from
    // any class, but schema just don't allow use to have full inheritence using either groups
    // or complexTypes. Thus we have taken a middle rode. If someone wants to key me into a
    // better way to represent this, I'd be happy to listen. =b.t.
    //
    // UPDATE: partial solution to the above: as of 13-Mar-2003 we now write BOTH a complexType
    //         AND a group declaration for interfaces AND classes which are inherited from.
