RFC requirements for relative CNAME targets?

My apologies--sent mid-message!

I know that for the following record in example.com's zone file:

host.example.com.  IN CNAME otherhost

BIND will return:

host.example.com. <TTL> IN CNAME otherhost.example.com.

Is this behavior required anywhere in the RFCs, or would

host.example.com. <TTL> IN CNAME otherhost.

be equally valid from an RFC perspective?  Obviously this would also
pertain to NS, MX, SRV, PTR, etc. records.
