queryport-pool-ports and queryport-pool-updateinterval obsolete in BIND 9.5?

[ivan jr sy]

Hi all,

I am wondering why queryport-pool-ports and queryport-pool-updateinterval 
syntaxes are described and documented in BIND 9.5 ARM while it is obsolete'd in 
the code?

I wish to be educated as to why (if its deprecated forever), and perhaps ideas 
(website links) on the new implementation/replacement syntax for BIND 9.5.0-P2 
++

Thanks!
