[DUG] Can anyone explain this one?

[Jolyon Smith]

OK, then I suppose another possibility is that whatever is getting the text
representation of your xml document to include in your request content is
doing it by grabbing the root node of the document "as text/string" rather
than the complete xml document.  In pseudo code:

  httpRequest.Content.AsString := xmldoc.RootNode.AsString;

vs

  httpRequest.Content.AsString := xmldoc.AsString;

i.e. It may not be your HTTP code or whatever components you are using per
se (it is highly unlikely that the HTTP component is deliberately and
selectively checking for xml content and then doing a surgical strike to
cleanly remove the prolog from that xml), but rather the code that
assembles the request to send via that HTTP component is not getting the
xml in quite the correct fashion, despite the actual source xml "dom"
itself being correct and complete.

I hope that makes sense.  :)
