Yes of course. But let user decides what's an appropriate content. 
Perhaps a bit stupid example, but consider an image depicting an em-tag. 
The logical alt-text is "<em>" which will unnecessarily be removed.

I consider it unlikely that users will bring tags into the alt-text 
anyway. And if there is some chance it's on purpose. So why bother 
stripping?

Duh, so no way to turn off unwanted title-attibutes? That's my main 
concern. I'm for alt-attribues in every image, but see absolutely no 
virtue in duplicating the-alt attribute in the title-attribute. *)

Ahem, I think this is a serious issue. It seems that some folks here 
care about accessability, some even mention laws. I really think that 
Typo3 should have some built-in support for both alt- and 
title-attribute in these core elements - and of course in the RTE. 
Doesn't mean it has to be in 3.6, but it'd be a shame if it isn't in 3.7.

Perhaps one of the devs with CVS acces could check out Volker's 
extension and see if it is reasonable code. If yes, how can it be 
extended to allow for a title-attribute.

Dunno, what's the procedure now, but perhaps Volker can provide a patch.
