dfxml:id 

A unique identifier for the file. It is distinct to both the input data and
the process parameters of the generating tool. (It is commonly defined by incrementing a
global counter in walk-encounter order of each file and directory.) This element is used
instead of the XML "id" attribute and the XML Schema "ID" attribute because one might wish
to preserve a fileobject's ID when it is transferred into another document (e.g. as an
original_fileobject). Using either of the more elementary ID attributes would disallow
preserving an ID if it was suddenly not a unique value.
