Can an Android Service have multiple Permissions?

I have a service which both downloads a file and saves it, and it seems I can only specify one permission.

<service android:enabled="true"
            android:name=".DownloadService" android:permission="android.permission.INTERNET">            
</service>

or

<service android:enabled="true"
            android:name=".DownloadService" android:permission="android.permission.WRITE_EXTERNAL_STORAGE">            
</service>

I need both.
