This documents new counterX/latch_mode* and counterX/countY/latched_count* attributes. The counterX/signalY/*_available are moved to the counterX/countY/*_available section similar to the way we already have The counterX/*_component_id and The counterX/signalY/*_component_id grouped together so that we don't have to start a 3rd redundant section for device-level *_available section.
