MS Office XML "Binary Key"

Hi All,

I have been reading Brian Jones' blog daily for the past few months, as I
am interested in MS' XML support in Office (I work for a large company were
Office is the standard and part of my job is looking into XML editing tools
for end users).  This weeks hot topic has Brian refuting claims of a
"binary key" in MS' XML format (
http://blogs.msdn.com/brian_jones/archive/2005/10/17/481983.aspx ).  I was
wondering if anyone here actually seen this key and how it could possibly
cripple any XML exported out of Office.
