The XML Declaration is not a processing instruction, as others have
noted.  However, MSXML 3.0 (and I think 4.0) treats it as a processing
instruction. 

You can assign an XML Declaration to an MSXML DOM by adding a processing
instruction to the DOM _before_ adding anything else:

var pi=xmldoc.CreateProcessingInstruction("xml"," version='1.0'
encoding='ISO-8859-1'");
xmldoc.appendChild(pi);

This PI must be the first thing in the DOM - no whitespace, nothing else
- or MSXML will ignore it.  

I don't currently have a functional MSXML parser, so this description is
based on old notes, but hopefully it will help.

There is also an excellent book, Unicode: A Primer, by Tony Graham,
which explains a lot of encoding issues, though it isn't focused on XML.
