	BIND 4 and BIND 8 leak data between zones.  This is a BUG in BIND 4
	and BIND 8 and in unavoidable due to the internal data structure
	used.  BIND 9 was specifically designed to eliminate this bug.


> Dear admins,
> When someone asked a named-xfer under bind8 he received also the NS RR in the

> eems not to work anymore under BIND9. All subdomains must be defined with NS 
> RR explicitely in the zone file, the information is not added. 
> Is this a new or normal behaviour of bind 9. Can we add some option to enable
>  this feature ??
