But what we *don't* know is whether the order of the umpteen identical 
tags in the XML has any significance in terms of the original data, 
although the OP seems intent on assigning some significance to that order 
without any basis for doing so.

Consider the following tuple:

t = (tuplemember_1, tuplemember_2, .... tuplemember_n)

Can we safely assume that if the tuple is ever converted to xml, either 
now or at some future date using whatever the code implementation is 
then, that the order of the items will be preserved:

<tuple>
  <item>tuplemember_1</item>
  <item>tuplemember_2</item>
....
  <item>tuplemember_n/item>
</tuple>

And if we're reading that xml structure at some point in the future, is 
it safe to assume that the tuple members are in the same order in the xml 
as they were in the original tuple?

For sanity <item> should have an attribute specifying the sequence of the 
item in it's tuple.
