That was my point. On the other hand, Applications people (like  
myself) that work with directory services and similar see risk for  
data corruption issues and extremely hard to debug chasing of RRs if  
the DNAME has a target outside the zone the record resides in. I.e.  
if the DNAME reference a record in the same zone the DNAME resides  
in, one is safe for these kind of problems. If not, one can end up in  
situations that should be studied a bit more.
