They are adjacent to the values that are allocated in the 1.12 spec; the
USB web site describes a process for asking for new fields to be defined
in that space.
Whether they are being used properly, is what I'd like to ensure; I have
a comment or two in the report data structure source I have that would
give me insight as to whether they are using them correctly. If not, I
want to complain at them...

That would be greatly appreciated. The values are all in the digitizer
page.
