> Currently Catalyst supports encoding custom classes represented as Java Beans
> (among others). This Java Bean implementation depends internally on
> Catalyst’s ObjectType extension of DataType. Right now, this class is private
> to the sql package [1]. However, its private scope makes it more difficult to
> write full custom encoders for other classes, themselves perhaps composed of
> additional objects.
> Opening this class as public will facilitate the writing of custom encoders.
