 From RFC 1034 - Domain names - concepts and facilities:
Of course, by the robustness principle, domain software should not fail
when presented with CNAME chains or loops; CNAME chains should be 
followed and CNAME loops signalled as an error.

http://www.faqs.org/rfcs/rfc1034.html

"Domain names in RRs which point at another name should always point at 
the primary name and not the alias. This avoids extra indirections in 
accessing information" is NOT a MUST
