I agree with Boris here. A possibly interesting case might be when the 
element is inline, but that might be more due to the inline model.

Eg: 
Should really 
span {border-style: solid; content: "Logo: " url(xyzcompany-logo)}
flow the border through the image of its content-property while it should 
not if the content property only held the image? 

Assuming that the above example should render a different height than 
span {border-style: solid; content: url(xyzcompany-logo)}
i think it means the interpretation of the span element is rather
different. 

CSS 2.1 firmly defines "replacedness" as a function of the markup element.
With the above definition the first case suggests the parts of the content 
value are similar to children in the document tree of the span node, while 
in the second the span "consists" of the content property. 

Personally i would prefer viewing an element with a valid content value 
as if it was replaced, but i am not sure such a distinction needs to 
be made explicit.
