statistics-channels /xml/v2 is removed but still documented
ARM contains documentation of statistics-channels format of /xml/v2. But code does not allow such format anymore. Only /xml/v3 and /json/v1 are supported in code.
BIND version used
BIND 9.11.4-RedHat-9.11.4-2.fc27 It seems present also in devel version
