Can an NS point to a CNAME

[Phil Mayers]

All,

We've had a report this morning that a user can't resolve:

71.225.219.134.in-addr.arpa PTR

...I think this is because the parent zone NS records point to CNAMEs. I 
can see references to (much) older versions of bind not following such 
delegations, but I'm not getting anything logged at the nameserver.

Is this still the case (that NS->CNAME is invalid)?
