+- `extra_claims` `(map[string]string: optional)` - A set of key-value pairs that
+  will be provided as extra identity claims for workloads. You can use the keys
+  as [user claims in Vault role configurations][vault-jwt-user-claim]. The
+  values are interpolated. For example, if you include the extra claim
+  `unique_id = "${job.region}:${job.namespace}:${job.id}"`, you could set the
+  user claim field to `/extra_claims/unique_id` to map that identifier to an
+  entity alias. The available attributes for interpolation are:
+
+  - `${job.region}` - The region where the job is running.
+  - `${job.namespace}` - The job's namespace.
+  - `${job.id}` - The job's ID.
+  - `${job.node_pool}` - The node pool where the allocation is running.
+  - `${group.name}` - The task group name of the task using Vault.
+  - `${task.name}` - The name of the task using Vault.
+  - `${node.id}` - The ID of the node where the allocation is running.
+  - `${node.datacenter}` - The datacenter of the node where the allocation is running.
+  - `${node.pool}` - The node pool of the node where the allocation is running.
+  - `${node.class` - The class of the node where the allocation is running.
+  - `${vault.cluster}` - The Vault cluster name.
+  - `${vault.namespace}` - The Vault namespace.
+  - `${vault.role}` - The Vault role.
