Well it still won't read it in. It will only read it in if the encoding
string is not present. I assume that means its not in ISO-8859-1. I think
I might be starting to understand it. If I do, then I think what everyone
is saying is that I cannot start with an XML template, rather, I have to
create the XML document completely over again, with the ISO-8859-1 encoding
standard from the start and then hopefully the UPS text encoding will stay
preserved when the node is added.

So, I can't take an existing DOM in whatever originally encoding it was,
even UTF-8, modify it and save it in a differnet encoded byte stream?

Unfortunely, UPS requires the XML document be in a specific format with a
certain text element being very specific. I'm not in control of their
parser or their requirements.
