option=com_mobilejoomla > Smartphone Settings
'use XML-Header' and 'xmlns in HTML-Header'
if You set both to TRUE nothing is added to the document.
if You set either one or the other to FALSE, it will show up before <head>
if You set either one or the other to TRUE, it will not be inserted.
In addition, I really would appreciate to get adviced for recommended settings in this place, as I didn't have much of aclue - besides checking 'm.mydomain.de' by
validator.w3.org, which is definitely a good idea for testing.
Thanks much for any hint!
