+This XML defines a list of UIDs for OEMs to register as shared UIDs. They will be registered at the
+start of the system, which allows OEMs to create services with these UIDs. The range of these UIDs
+must be in the OEM reserved range.
+
+OEM must provide a preloaded app that is installed at boot time to retain the newly registered UID
+by adding a android:sharedUserId tag in the manifest of the preloaded app, with the value of the tag
+set to the name of the UID defined in this config file. Otherwise, the uid will be cleared at the
+end of the boot and this config file will take no effect.
+
+- The "name" XML attribute refers to the name of the shared UID. It must start with "android.uid.".
+- The "uid" XML attribute refers to the value of the shared UID. It must be in range [2900, 2999].
+
+Example usage
+    <oem-defined-uid name="android.uid.vendordata" uid="2918"/>
+    Indicates that a shared UID named "android.uid.vendordata" will be added to the system with the
+    UID of 2918.
