+  The resource configuration now supports typed attributes with the following types:
+  - `string` (default)
+  - `bool`
+  - `int`
+  - `double`
+  - `string_array`
+  - `bool_array`
+  - `int_array`
+  - `double_array`
+
+  Example configuration:
+  ```yaml
+  service:
+    telemetry:
+      resource:
+        attributes:
+          - name: service.name
+            value: my-collector
+          - name: feature.enabled
+            value: true
+            type: bool
+          - name: retry.count
+            value: 5
+            type: int
+          - name: latency.threshold
+            value: 12.5
+            type: double
+          - name: owners
+            value: [team-a, team-b]
+            type: string_array
+          - name: success.flags
+            value: [true, false]
+            type: bool_array
+  ```
+
+  The legacy inline attribute map format (string-only) is still supported for backward compatibility:
+  ```yaml
+  service:
+    telemetry:
+      resource:
+        service.name: my-collector
+        host.name: collector-host
+  ```
+
+# Optional: The change log or logs in which this entry should be included.
+# e.g. '[user]' or '[user, api]'
+# Include 'user' if the change is relevant to end users.
+# Include 'api' if there is a change to a library API.
+# Default: '[user]'
+change_logs: [user]
