dnssec-guide should mention use of validate-except
Description
Add use of validate-except { string; }
to DNSSEC guide.
From discussion on bind9 users list, the recommendation to not use dnssec-validation no
but instead use validate-except { string; }
would ideally be mentioned in the DNSSEC guide (bind9/doc/dnssec-guide) within the ARM.
Request
Within DNSSEC guide where dnssec-validation
is discussed for troubleshooting, add some information about the use of validate-except { string; }
with some examples.
Suggest too that dnssec-validation](https://bind9.readthedocs.io/en/v9.18.20/reference.html#namedconf-statement-dnssec-validation) statement also mention validate-except
. Yes I see validate-except is immediately below it, but without the dotted line it may not be seen.
