Thanks for this well-written and clear document.  I have only one question:

-- Section 4.1 --

   When honoring the uncacheable file data attribute, clients SHOULD NOT
   delay transmission of WRITE data for the purpose of combining
   multiple WRITE operations or improving efficiency.

I wonder about the SHOULD NOT here.  For write caching, there's a real issue of
corrupting the file, so why is this not "MUST NOT"?
