Sorry if I came off as condescending, it looked that way when I read it again. The rfcs are 1034 and 35 and are very interesting reads. 5321 is good too. For example, did you know that you don't need an mx record for email? If none is present, it will default to the a record. DNSSEC is in 4034, among others. Also, I think maybe more explanation about the main benefit of CNAMES, a virtual host based setup where many domains point to the same IP.
