This draft refers to RFC1853 for IP-in-IP encapsulation which was 
Informational. The more useful reference would be to RFC2003, which is 
Standards Track.

RFC2003 appears to cover most of the issues in this document, where 
IPsec-specific issues are further covered already in RFC2401 and its 
pending update.
