Section 4.2.6 says:

         [...] If BGP installs
         a route of one of these types in the VRF, and if that route is
         selected for redistribution into OSPF, it will be advertised by
         OSPF in either a type 3 or a type 5 LSA, depending on the
         domain identifier.

It should say:

         [...] If BGP installs
         a route of one of these types in the VRF, and if that route is
         selected for redistribution into OSPF, it will be advertised by
         OSPF in either a type 3, type 5, or type 7 LSA, depending on the
         domain identifier and the type of area the PE/CE link belongs to.

Notes:

Suggested because reading 4.2.6 is contradictory with the following:

4.2.8.1. External Routes

[...]If the route is advertised, and the PE/CE link belongs to a NSSA area, it is advertised in a type 7 LSA.[...]
