DNSSEC and Bind 9.3.6

[alexander at nautae.eti.br]

Hi.

Some people here have said that the option 'managed-keys' only exists in
the bind 9.7 version.

That's ok, that's right, I'm going to upgrade my Bind.

But at this time would be very nice if it would be possible to use DNSSEC
with Bind 9.3.6 version, just to test some particular parameters here.

So, is that possible in any way to use DNSSEC with Bind 9.3.6?

Is there any documentation to follow?

What are the general important DNSSEC differences in these versions (9.3
and 9.7)?

Is that a really good idea install the Bind newer version considering
these differences?

Sorry the basic questions... it's just because I think it's a good idea
share my worries in this case.
