This still is not a reason. When stylesheets are off that means that  
the UA is using the UA stylesheet to present the quotations. This  
thread started by Simon is designed to ensure UAs have a sufficient  
stylesheet to present quotations in a familiar manner to anyone in the  
World. So:

will be rendered properly using the UA stylesheet. Therefore I still  
haven't heard a reason why we shouldn't let the styling of quotations  
be handled on the presentation layer and not in the HTML document.

I think that would be a suitable definition (broadening it beyond that  
would lead likely to undesirable errors).

Such a legacy error handling approach should work whether quotations  
are immediately inside or immediately outside the element (ignoring

The rendering rule to avoid duplicating quotations when adding them  
with CSS should be for legacy support only IMO. This has been  
discussed at length in this thread[1][2]. It is not entirely clear  
this is the best way forward, but it could be. It deals well with  
legacy content and legacy browser targeted content. Once IE8 is  
released it will still be some time before authors can successfully  
use quotations as HTML4.01 intended. Supplementing the CSS to meet  
some of the other various locale/language conventions discussed in  
this thread is also important (such as handling punctuation kerning,  
collapsing of multiple terminating quotation marks and supporting  
alternate quotation presentation based on word and character length) .

Take care,
