Yes, it is there!  Thank you.  I had looked a few folders back from the 
instance but not at the root.  That's great.  Is there any way to get the 
transaction associated with the proper object?  I tried the method listed in 
a recent zopelabs.com recipe:

get_transaction().note('/'.join(foo.getPhysicalPath()))


To no avail (though it didn't make much sense to me to begin with).  If this 
is not directly possible, where can I find more information about delving 
into the transaction machinery to find the transactions specific to this 
object?  My web and mailing list searches have been pretty fruitless, and the 
source code for the transaction machinery is pretty opaque to me.  Thanks 
again.
