+  Example implementation:
+
+  - Extract the file path from the URL.
+  - Use fs.stat() to retrieve the file metadata.
+  - Format the response body in the desired XML format with the properties and metadata.
+  - Set the response status code to 207 if successful or an appropriate error code if the file is not found or encountered an error.
+  - Set the Content-Type header to indicate the XML format.
+  - Return the response.
