=head1 DESCRIPTION
This class simply provides a mechanism for discovering and loading a sub-class
-for a specific version Oracle backend. It should be transparent to the user.
+for a specific version Oracle backend. It should be transparent to the user.
+
+For Oracle major versions < 9 it loads the ::Oracle::WhereJoins subclass,
+which unrolls the ANSI join style DBIC normally generates into entries in
+the WHERE clause for compatibility purposes. To force usage of this version
+no matter the database version, add
+
+ __PACKAGE__->storage_type('::DBI::Oracle::WhereJoins');
+to your Schema class.
