+/* The general design is to use one relational table per objectclass. This is
+ * complicated by objectclass inheritance and auxiliary classes though.
+ *
+ * Attributes must only occur in a single table. For objectclasses that inherit
+ * from other classes, attributes defined in the superior class are only stored
+ * in the superior class' table. When multiple unrelated classes define the same
+ * attributes, an attributeSet should be defined instead, containing all of the
+ * common attributes.
+ *
+ * The no_set table lists which other attributeSets apply to the current
+ * objectClass. The no_attrs table lists all of the non-inherited attributes of
+ * the class, including those residing in an attributeSet.
+ *
+ * Usually the table is named identically to the objectClass, but it can also
+ * be explicitly named something else if needed.
