+  <pre>Enumerate Changes to a ResourceRecordSet collection.
+
+Args:
+  project: string, Identifies the project addressed by this request. (required)
+  managedZone: string, Identifies the managed zone addressed by this request. Can be the managed
+zone name or id. (required)
+  pageToken: string, Optional. A tag returned by a previous list request that was truncated.
+Use this parameter to continue a previous list request.
+  maxResults: integer, Optional. Maximum number of results to be returned. If unspecified, the
+server will decide how many results to return.
+  sortBy: string, Sorting criterion. The only supported value is change sequence.
+  sortOrder: string, Sorting order direction: &#x27;ascending&#x27; or &#x27;descending&#x27;.
+  x__xgafv: string, V1 error format.
+    Allowed values
+      1 - v1 error format
+      2 - v2 error format
