# If more than two resources are given, Pacemaker will treat this as a
# resource set.  Originally this was an Array, but then we added
# support for it alternatively being a String, in order to support
# parentheses in the constraints passed to Pacemaker.  (Parentheses
# allow sub-groups of resources which can be started in parallel.)  We
# have kept Arrays for backwards compatibility, but they are
# deprecated, because it's better if the responsibility of
# understanding the structure of this part of the crm configure string
# is delegated to Pacemaker.
