IE has a crappy default security model for it in some versions, where you  
have to turn *on* a sensible mode. But I don't think it is the place of  
this spec to decide *the* security model - if people want to use scripts  
that copy and paste stuff that should be OK conformance wise, although  
there are a bunch of things that should generally be turned off for  
security. I plan to sprinkle more warnings through the spec.

I don't think Opera is in any hurry to emulate IE's default security model  
described above. But pointing out to authors that they *should not* rely  
on certain functions if they are not trusted, and that implementations  
*should* block assorted things, is IMHO the right way to go. Implementors  
sometimes sit down and work on security models together, we sometimes  
differentiate. We also have variable models according to customer needs,

Yeah, I am thinking of reordering the examples because of that problem,  
and clarify that the use cases may not all be met by version 1.

Thanks for the comments
