I only included some of the suggestions for the rule conflicts & errors
part from Hannes for now as these are more important to be correct and
understandable for the release.

 HA rules can impose rather complex constraints on the HA resources. To ensure
 that a new or modified HA rule does not introduce uncertainty into the HA
 stack's CRS scheduler, HA rules are tested for feasibility before these are
-applied. If a rule does fail any of these tests, the rule is disabled until the
-conflicts and errors is resolved.
+applied. For any rules that fail these tests, these rules are disabled until
+the conflicts and errors have been resolved.
 
 Currently, HA rules are checked for the following feasibility tests:
 
-* A HA resource can only be referenced by a single HA node affinity rule in
-  total. If two or more HA node affinity rules specify the same HA resource,
-  these HA node affinity rules will be disabled.
+* An HA resource can only be part of a single HA node affinity rule.
 
-* A HA resource affinity rule must specify at least two HA resources to be
-  feasible. If a HA resource affinity rule specifies only one HA resource, the
-  HA resource affinity rule will be disabled.
+* An HA resource affinity rule must have at least two HA resources.
 
-* A HA resource affinity rule must specify no more HA resources than there are
-  nodes in the cluster. If a HA resource affinity rule specifies more HA
-  resources than there are in the cluster, the HA resource affinity rule will
-  be disabled.
+* A negative HA resource affinity rule cannot specify more HA resources than
+  there are nodes in the cluster. Otherwise, the HA resources do not have
+  enough nodes to be separated.
 
 * A positive HA resource affinity rule cannot specify the same two or more HA
   resources as a negative HA resources affinity rule. That is, two or more HA
-  resources cannot be kept together and separate at the same time. If any pair
-  of positive and negative HA resource affinity rules do specify the same two
-  or more HA resources, both HA resource affinity rules will be disabled.
+  resources cannot be kept together and separate at the same time.
 
-* A HA resource can only be referenced by either a HA node affinity rule or HA
-  resource affinity rules, but not both at the same time. If there is at least
-  one HA node affinity rule and at least one HA resource affinity rule, which
-  specify the same HA resource, these rules will be disabled.
