Yes, I do use loadXML and not load.  I have read this article about 10 times
already.  However, reading again after your and others posts has made this a
little clearer to me.  It appears I'm reading an existing XML document with
LoadXML.  That document is thus read in by default as UTF-8 because there is
no encoding declaration.  Then I receive an XML response from a second
party.  I try and move one node from that XML document into my new one where
that node is actually in ISO-8859-1.  It automatically converts the
ISO-8859-1 node to UTF-8 otherwise it wouldn't be able to stick it in the
XML document in the first place and the whole thing quits working.

Conclusion:
I have to create a brand new XML document and ensure it is ISO-8859-1 from
the start.  Define the elements and then move over the text from the XML
response from a second party.  And, then it will remain ISO-8859-1

Thanks for your help.  I'm going to go try this now.
