Note that because javadoc has an exclusively source level
        perspective, javadoc will be broken if generic support does
        not roll out with generics.

        Impact on Doclet API
                Two new sub-interfaces of Type will need to be added.
                Their exactly structure will need to be carefully
                considered so that existing doclets "fail" as gently
                as possible. Several other methods will need to be
                added to MethodDoc, ClassDoc, Type, ...
                See discussion of class definition vs class use, at
                the bottom.

        Impact on Doclet API implementation (aka javadoc tool)
                This requires that:
                * we complete (or re-implement) the Doclet API
                  implementation on the new compiler.
                * we extend it with the new API functionality.

        Impact on Standard Doclet
                This change will have some impact on just about every
                corner of the Standard Doclet.
