How to add these headers to a xml response

Hi,

I need to create something like this:

<?xml version="1.0" encoding="UTF-8"?>
<Container>
<id>aQlfVHX+qPM</id>
<lifetime>2009-09-19T08:14:55Z</lifetime>
</Container>

The response should contain the next headers:

Content-Type=`application/vnd.3gpp+xml`
Authentication-Info={rspauth=`xxxxxxxxxxx...xxxxxxxxxxx`,qop=`auth-int`,cno nce=`xxxxxxxxxxxxxxxxxx....xxxxxxxxxxxxx`,nc=`000
00001`}

You should just be able to set headers['foo'] in your controller.
