Summary:
--------
We would like to propose adding usages to the HID spec to better support styli used with digitizers.         

Background:
-----------
Styli used with current digitizers often have two barrel switches and/or may support a serial number capability.

Proposal:
---------
All changes are localized to Chapter 16 Digitizers (0x0D).

New usages to be added to Table 18: Digitizer Page

5A	Secondary Barrel Switch		MC	16.4
5B	Transducer Serial Number	SV	16.3.1

Additions referenced by the above usages:
Section 16.4 Digitizer Switch Usages


Secondary Barrel Switch		MC - A second non-tip button located on the barrel of a stylus further from 
				     the tip than the Barrel Switch. Its function is typically mapped to a 
			   	     system secondary or tertiary button.

Section 16.3.1 Digitizer-Specific Fields

Transducer Serial Number	SV - A unique persistent identifier provided by the transducer currently in use.Response:---------
