9.11.3-S1 ARM doesn't include syntax for ECS options
Summary
The 9.11.3-S1 ARM describes the various options related to recursive ECS support but they are not listed in the options grammar.
They do exist in isccfg, so this seems to be an issue in the (automated?) export of the configuration grammar for the ARM.
