/* 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.
