Is that because idle-state-name and local-timer-stop should not be
defined for domain-idle-states or are you just clearing out the
dtbs_check warning?

According to cpu-capacity.txt local-timer-stop seems to have been a
property relevant for clusters in the past, was this a mistake in the
binding or did something change when this was moved to
domain-idle-states?
