Then obviously something is wrong on *your* side. Or do you happen to use
loadXML()? In which case I recommend to read the SDK documentation and the
MSDN article about encodings
(<http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnxml/htm
l/xmlencodings.asp>).

No, that's not the case. Start with a document like the one above, replace
the document element with what you need, and that's it.

You can. How this works depends on the implementation of the XML serializer
that you use with your DOM.

Is this requirement documented somewhere (web link)?
