One more comment on this draft:

The RedirServiceProvider resource record has a field to store the Node-ID of
the service provider, but I think that it would be better to use a Destination
list instead.  One of the reasons is that the provider can be a RELOAD client
without direct routability (see -base section 3.2.1, second bullet).  There is
also future extensions that could require a Destination list.  So I propose to
change the definition to this:

               struct {
                 RedirServiceProviderExtType   type;
                 Destination                   destination_list<0..2^16-1>;
                 opaque                        namespace<0..2^16-1>;
                 uint16                        level;
                 uint16                        node;
                 uint16                        length;

                 select (type) {
                     /* This type may be extended */
                 } extension;

               } RedirServiceProvider;
