+       Numeric types with "_wm" suffix are watermarked numbers.  These are compound
+       values containing a current value, and a low and high water mark for the reporting
+       interval.  The low and high water marks are set to the current value at the
+       beginning of each interval and track the minimum and maximum values of the statistic
+       over the interval respectively.
+
+       Access rights for configuration elements:
+
+           RO => Read Only
+           RC => Read/Create, can be set at create time only, read-only thereafter
+           RW => Read/Write
+
+           If access rights are omitted for a configElement, they are assumed to be RO.
