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.[...]
