-* proper command-line tool for schema generation and export
-* deprecated the interface cirrus.hibernate.Persistent (due to popular demand)
-* changes to hibernate-mapping DTD (required to support optional Persistent interface):
-- deprecated <property type="package.PersistentClassName"/> in favor of <many-to-one class="package.PersistentClassName"/>
-- deprecated <element type="package.PersistentClassName"/> in favor of <many-to-many class="package.PersistentClassName"/>
-- deprecated <property role="..."/> in favor of <collection role="..."/>
-- deprecated <element role=".."/> in favor of <subcollection role="..."/>
-- deprecated <association> in favor of <one-to-many>
