If response bufffering is not enabled then setting the content type after
sending the content is too late.

Do it at the start of the page.

If you are include an <?xml declare at the top of the xml make sure that you
don't have any blank lines preceeding the xml either.

While you are at it make sure you get the character encoding correct by
setting the Response.CodePage = 65001 and adding Response.CharSet = "UTF-8"
to your code as well.

Don't just do it, do it right.
