+                    type are discouraged because of difficulty describing its usage
+                    when embedded in APIs. 1. Ignored fields.  It includes many fields
+                    which are not generally honored.  For instance, ResourceVersion
+                    and FieldPath are both very rarely valid in actual usage. 2. Invalid
+                    usage help.  It is impossible to add specific help for individual
+                    usage.  In most embedded usages, there are particular restrictions
+                    like, \"must refer only to types A and B\" or \"UID not honored\"
+                    or \"name must be restricted\". Those cannot be well described
+                    when embedded. 3. Inconsistent validation.  Because the usages
+                    are different, the validation rules are different by usage, which
+                    makes it hard for users to predict what will happen. 4. The fields
+                    are both imprecise and overly precise.  Kind is not a precise
+                    mapping to a URL. This can produce ambiguity during interpretation
+                    and require a REST mapping.  In most cases, the dependency is
+                    on the group,resource tuple and the version of the actual struct
+                    is irrelevant. 5. We cannot easily change it.  Because this type
+                    is embedded in many locations, updates to this type will affect
+                    numerous schemas.  Don't make new APIs embed an underspecified
+                    API type they do not control. \n Instead of using this type, create
+                    a locally provided and used type that is well-focused on your
+                    reference. For example, ServiceReferences for admission registration:

+                    when embedded in APIs. 1. Ignored fields.  It includes many fields
+                    which are not generally honored.  For instance, ResourceVersion
+                    and FieldPath are both very rarely valid in actual usage. 2. Invalid
+                    usage help.  It is impossible to add specific help for individual
+                    usage.  In most embedded usages, there are particular restrictions
+                    like, \"must refer only to types A and B\" or \"UID not honored\"
+                    or \"name must be restricted\". Those cannot be well described
+                    when embedded. 3. Inconsistent validation.  Because the usages
+                    are different, the validation rules are different by usage, which
+                    makes it hard for users to predict what will happen. 4. The fields
+                    are both imprecise and overly precise.  Kind is not a precise
+                    mapping to a URL. This can produce ambiguity during interpretation
+                    and require a REST mapping.  In most cases, the dependency is
+                    on the group,resource tuple and the version of the actual struct
+                    is irrelevant. 5. We cannot easily change it.  Because this type
+                    is embedded in many locations, updates to this type will affect
+                    numerous schemas.  Don't make new APIs embed an underspecified
+                    API type they do not control. \n Instead of using this type, create
+                    a locally provided and used type that is well-focused on your
+                    reference. For example, ServiceReferences for admission registration:
+                    https://github.com/kubernetes/api/blob/release-1.17/admissionregistration/v1/types.go#L533

+                        field access statement, such as desiredState.manifest.containers[2].
+                        For example, if the object reference is to a container within
+                        a pod, this would take on a value like: "spec.containers{name}"
+                        (where "name" refers to the name of the container that triggered
