Unqualified XML's and cfheader

I've been playing around with creating an XML file this morning from a plain .cfm page and came across an annoyance. Now I've done this loads but this morning I was creating my own Ajax functions which meant the cfm page had to return a fully qualfied as XML which was passed into Javascripts XML parser, but Js was passing an error. The test code was simple[xml.cfm] 1 The problem was CFHEADER adds a couple of blank lines to the top of the page meaning that the page did not pass as XML. Well thanks to Rob Wilkerson on CF-Talk the anser was obvious simple - use CFCONTENT 1 I did try a few other ways of surpressing the white space usin a variety of methods but nothing came close.
