+description: >
+    Implement to provide PEL event/error entry attributes.
+properties:
+    - name: Hidden
+      type: boolean
+      default: false
+      description: >
+          Hidden Error - This flag allows events to be placed in a system, but
+          remain hidden from the customer. This event log is visible to
+          development personnel only, e.g. hardware recovered error, etc. No
+          service action is required for this type of errors. In general, when
+          this value is used, the Error Action Flags has the value of
+          "Hidden Error". An event log with this value is used primarily for
+          error thresholding design/code debug or as a record to indicate an
+          error frequency or trend.
