Done.

[mark a. foltz, 2017/04/12 00:17:18]

Device model name

[zhaobin, 2017/04/18 06:58:27]

Done.

+  std::string model_name;
+
+  // The reported device type, e.g. urn:dial-multiscreen-org:device:dial:1

Won't this always be the same for DIAL devices?  I wonder if we need to include
this field, or just check that it matches the constant string when the device is
discovered.

[zhaobin, 2017/04/18 06:58:27]

Done.

+  std::string device_type;
+
+  // The application URL.

[mark a. foltz, 2017/04/12 00:17:18]

The DIAL application URL (used to launch DIAL applications).

[zhaobin, 2017/04/18 06:58:27]

Done.
