Specialization is the process by which new designs are created based on existing designs, allowing new kinds of content to be processed using existing processing rules.

Specialization allows you to define new kinds of information (new structural types or new domains of information), while reusing as much of existing design and code as possible, and minimizing or eliminating the costs of interchange, migration, and maintenance.
