Well, the whole point of an IE compatibility shim is that it is merely a 
work-around for IE's lack of native support. I wouldn't expect a 
compatibility shim to be fully compliant -- I'm sure it'll always be 
possible to find simple cases that fail. Dynamic manipulation in 
particular is not something I'd expect to be particularily successful, 
when the implementation is at the same level as the manipulation code.

For native implementations, requiring that authors link to a special 
stylesheet or whatever clearly isn't ok. However, if an author wants to be 
able to use WF2 features on a non-WF2 UA, he can install a compatibility 
shim, and thus get around the problem of lack of support.

But being able to use a shim doesn't affect the spec.

Does that answer your question?
