 Hi Jelte

 Replying to [comment:11 jelte]:

 Eek! Fixed. :)

 > The dynamic cast in the added test in message_unittest makes me think
 that this new method should probably go into the AbstractRRset interface
 as well.

 I wondered where to put it as well, as the RRSIGs are really handled only
 in the `RRset` class. But you tipped the balance in `AbstractRRset`'s
 favour. :) It also avoids the `dynamic_cast`, so I agree this is better.

 The method was also renamed to be more consistent with the rest of the
 RRSIG related methods of `AbstractRRset`.

 Also a minor change adding `virtual` to a method was made.
