+            - Cloud Labels are a flexible and lightweight mechanism for organizing cloud resources
+              into groups that reflect a customer's organizational needs and deployment strategies.
+              Cloud Labels can be used to filter collections of resources. They can be used to
+              control how resource metrics are aggregated. And they can be used as arguments to
+              policy management rules (e.g. route, firewall, load balancing, etc.).
+            - 'Label keys must be between 1 and 63 characters long and must conform to the following
+              regular expression: `[a-z]([-a-z0-9]*[a-z0-9])?`.'
+            - Label values must be between 0 and 63 characters long and must conform to the regular
+              expression `([a-z]([-a-z0-9]*[a-z0-9])?)?`.
+            - No more than 64 labels can be associated with a given resource.
+            - See U(https://goo.gl/xmQnxf) for more information on and examples of labels.
+            - 'If you plan to use labels in your own code, please note that additional characters
+              may be allowed in the future. And so you are advised to use an internal label representation,
+              such as JSON, which doesn''t rely upon specific characters being disallowed. For
+              example, representing labels as the string: name + "_" + value would prove problematic
+              if we were to allow "_" in a future release.'
