[Kea-users] Empty client-classes in config

Hi all,

I'm running into an issue with config parsing and empty lists. I have
a "client-classes" definition at the global level. We populate it via
includes, and not all instances will have classes defined, but rather an
empty list `[]`. This has worked for other properties, like "option-def"
or "shared-networks", but "client-classes" seems to have an issue with it
and throws the following error in validation:

Syntax check failed with: /etc/kea/kea-dhcp6.conf:87.28: syntax error,
unexpected ], expecting {

Is this an expected behaviour, or am I doing something wrong?

Thanks
– Diogo
