Good point, I also thought about it.

Of course this would be easy, but a user complaining invalid XHTML
output, because of _his own_ setting disableAltText is a little bit like
he would complain TYPO3 not fixing _his own_ invalid HTML template.

Additionally config.xhtml_cleaning is taking care of dublicate and
missing alt tags. So the patch just fixes the behavior promoted in the
documentation.

But I'm happy to provide a new patch, if you still think it's necessary :)
