The {@inheritDoc} tag can be used to inherit the documention of corresponding elements in the super class or interface, reducing the amount of copying and pasting needed to document a hierarchy of classes. Unfortunately, {@inheritDoc} does not seem to work for type parameters, e.g.

/**
 * @param <S> some type
 */
class Parent<S> {...}

/**
 * @param <S> {@inheritDoc}
 */
class Child<S> extends Parent<S> {}

doesn't produce any documentation for S in Child.

This behavior would help encourage documenting the role of type parameters.
