That should absolutely work. The sample code below works for me.
You'll probably want to test with Firefox because it renders XML
nicely.

renderContentOn: html
	html anchor
		callback: [
			self requestContext respond: [ :response |
				response
					contentType: 'text/xml';
					nextPutAll: '<?xml version="1.0"
encoding="UTF-8"?><hello><world/></hello>' ] ];
		with: 'XML'
