Is it, in any way, possible to disable the browsers execution of script inside a block/section/element ?

My scenario is, that I'm letting my (future) users create "rich content" (using CK-editor). Content that wil later be shown to other users - with all the dangers that imply: xss, redirection, identity theft, spam and what not...

I've, more or less, given up on trying to "sanitize" the incomming XHTML, after seeing how many known "vectors of attack" there are: http://ha.ckers.org/xss.html

What I'm really looking for is something like:

< div id="userContent">< scriptOFF>

suspect HTML

< /scriptOFF>< /div>
