When Cascading Style Sheets (CSS) style an inclusion element (like a 
'frame', 'object', or 'img' element), the included content must not 
inherit the style of the inclusion element. Thus a CSS 'color' value on 
a 'frame' element must have no effect on the document in the frame.

I stop short of saying that an inclusion element's style must not 
affect the included content. For example, if included content has a 
non-opaque background and the inclusion element has a visible 
background, the latter should show through the former.
