The document you cite is the Mircosoft
standard; its usual URL is:
http://msdn.microsoft.com/en-us/windows/hardware/gg463006.aspx#EMLAC

I don't know of a more recent document from
Microsoft.  The more recent standard is the
Broadcast Wave Format (BWF), and a related
standard RF64.  RF64 was last revised in 2009,
and uses the same 19 Channel Mask
definitions.  The only change was that:
    #define SPEAKER_RESERVED 0x80000000

was renamed SPEAKER_ALL.

The European Broadcasting Union (EBU) has
a workgroup called ECA-BWF which is looking
at how to update the BWF/RF64 file format.

Regards,
Martin
