This is regarding issue the feature request #397 and the implementation of the always_null zone.

The always_null zone does not seem to work inside a view:

server:
  access-control-view: 127.0.0.0/8 "local"
view:
  name: "local"
  local-zone: "example.com" always_null

gives the error error: local-zone type: expected static, deny, refuse, redirect, transparent, typetransparent, inform, inform_deny, always_transparent, always_refuse, always_nxdomain, noview or nodefault, while there is no problem if the local zone is in the server section.

The documentation indicates that the local-zone inside a view should Ha[ve] the same types and behaviour as the global local-zone elements, however it is not implemented in configparser.y. always_nodata and always_deny also seem to be missing.

I have tested version 1.13.1 on Debian and Arch.
