 |           # systems are expected to put that etag in the request to `setIamPolicy` to |

 |           # **Important:** If you use IAM Conditions, you must include the `etag` field |

 |           # | 
 |           # Any operation that affects conditional role bindings must specify version |

 |           # * Getting a policy that includes a conditional role binding | 
 |           # * Adding a conditional role binding to a policy | 
 |           # * Changing a conditional role binding in a policy | 
 |           # * Removing any role binding, with or without a condition, from a policy | 
 |           #   that includes conditions | 
 |           # | 
 |           # **Important:** If you use IAM Conditions, you must include the `etag` field |

 |       # | 
 |       # | 
 |       # A `Policy` is a collection of `bindings`. A `binding` binds one or more | 
 |       # `members` to a single `role`. Members can be user accounts, service accounts, | 
 |       # Google groups, and domains (such as G Suite). A `role` is a named list of | 
 |       # permissions; each `role` can be an IAM predefined role or a user-created | 
 |       # custom role. | 
 |       # | 
 |       # For some types of Google Cloud resources, a `binding` can also specify a | 
 |       # `condition`, which is a logical expression that allows access to a resource | 
 |       # only if the expression evaluates to `true`. A condition can add constraints | 
 |       # based on attributes of the request, the resource, or both. To learn which | 
 |       # resources support conditions in their IAM policies, see the |

 |         # prevent simultaneous updates of a policy from overwriting each other. | 
 |         # It is strongly suggested that systems make use of the `etag` in the | 
 |         # read-modify-write cycle to perform policy updates in order to avoid race | 
 |         # conditions: An `etag` is returned in the response to `getIamPolicy`, and | 
 |         # systems are expected to put that etag in the request to `setIamPolicy` to | 
 |         # ensure that their change will be applied to the same version of the policy. | 
 |         # | 
 |         # **Important:** If you use IAM Conditions, you must include the `etag` field | 
 |         # whenever you call `setIamPolicy`. If you omit this field, then IAM allows | 
 |         # you to overwrite a version `3` policy with a version `1` policy, and all of | 
 |         # the conditions in the version `3` policy are lost. | 
 |     "version": 42, # Specifies the format of the policy. | 
 |         # |

 |         # are rejected. | 
 |         # | 
 |         # Any operation that affects conditional role bindings must specify version | 
 |         # `3`. This requirement applies to the following operations: | 
 |         # | 
 |         # * Getting a policy that includes a conditional role binding | 
 |         # * Adding a conditional role binding to a policy | 
 |         # * Changing a conditional role binding in a policy | 
 |         # * Removing any role binding, with or without a condition, from a policy | 
 |         #   that includes conditions | 
 |         # | 
 |         # **Important:** If you use IAM Conditions, you must include the `etag` field | 
 |         # whenever you call `setIamPolicy`. If you omit this field, then IAM allows | 
 |         # you to overwrite a version `3` policy with a version `1` policy, and all of | 
 |         # the conditions in the version `3` policy are lost. | 
 |         # | 
 |         # If a policy does not include any conditions, operations on that policy may | 
 |         # specify any valid version or leave the field unset. |
