Another interesting question is, what is expected, 
if the display property of a use is animated - 
does this mean, that the appearence of the 
embedded XHTML changes?
Because XHTML and CSS themselves do not really define, 
what is animatable or not, SMIL animation is not directly
applicable for XHTML+CSS (apart from the specific 
XHTML+SMIL note from the SMIL group), however if an 
animated property is inherited, the animation takes place 
in the well defined SVG environment.
As far as I can remember, for example Opera did or does 
something like a raster image of the XHTML fragment - could 
be difficult to apply animated properties to such an image
as it is difficult to use forms and similar interactive content
from XHTML pretty relevant for SVG authors - even
more than inherited, animated styling, because the functionality
is not available in SVG at all in contrast to the presentation
of simple text like 'Hello Kitty' ;o)

Note, that the appearence of the XHTML fragment may
change as well, if width and height of the foreignObject
are changed with animation, therefore to get
something useful, maybe one has to clone these things
anyway separately for any use reference.
