Sure, but a boolean is enough for that. The part I didn't get is the 3rd 
state "isEnabledViaScript". You can't really check if its enabled by 
JavaScript this way, and it shouldn't matter in any case. 

I think you were trying to work around the problem that changes in the link 
sheets have to recalculate the chain which determines which titled 
stylesheet to render by default. I don't see any other use for this code, 
but maybe I'm wrong.

Any site that provides alternative stylesheets and the user has actually 
selected them. Furthermore dynamic updates were broken, see testcase at

http://khtml.homeip.net/DOMlink.html

See the bit lengthy patch I just committed. It is itself not yet optimal as 
it causes more style selector recalculations than necessary, but thats not 
unintrusive to fix.
