[Boost-users] XML Serialization Traits Question

I have read both the Boost Serialization online documentation and the
archives of the Boost-Users mailing list looking for guidance, but I
haven't found anything relevant.  I see how to use BOOST_CLASS_TRACKING
and BOOST_CLASS_IMPLEMENTATION to remove version tracking attributes
from the XML tags.  
 
I want to go in the opposite direction.  I notice that the class_id and
version attributes only appear the first time an object of a particular
class is serialized.  I want to force the version attribute to appear in
every object's attribute list.
 
Do I need to derive a custom archive to do this?  I have looked at the
source code for serialization, but I have trouble plowing through all of
the macros, template expansions, and overloaded functions to locate the
specific part that controls whether class traits are stored as
attributes in a particular XML tag.
 
Thanks in advance,
Bill
