I don't top post as a rule, David T.

John,

The OP also said
===
I notice it when my file is processed by a separate tool, which
(understandably, IMO) fails when it encounters this exchange rate.
===
Notice "seperate tool"

So, do I have to dig backwards through the quotes now?

Which ones ?

Maybe he bought forward?

that does look wrong

>>>   </price:time>
>>>   <price:source>user:xfer-dialog</price:source>

I think the clue there is a human doing something rather than a price 
fetch from a bourse.

>>>   <price:value>-1/0</price:value>

as does that

>>> </price>
