+ * Users should never instantiate this class. It represents an attribute internal to
+ * an ObjectClass. If PHP supported inner-classes and variable permissions, this would
+ * be interior to class ObjectClass and flagged private. The reason this class is used
+ * and not the "real" class AttributeType is because this class supports the notion of
+ * a "source" objectClass, meaning that it keeps track of which objectClass originally
+ * specified it. This class is therefore used by the class ObjectClass to determine
+ * inheritance.
