I though this was a cool idea -- so much so that I experimented with it some
a couple weeks ago!
I though this would be a "poor mans solution" for scaling bit maps as well
as SVG. Unfortunately, it doesn't work!  Various recent flavors of IE and
Navigator get very confused.  The code doesn't validated either.  I then
looked up the 4.01 HTML specs, and the two choices for sizing things where
this technique would be valuable (tables, images, objects) are percentages
and pixels.  That's it.  Using percentages does allow images (SVG or GIF or
JPEG or PNG) to scale, but this only works one changes window size.  (So, in
effect, this technique allows one to shrink images, but not to grow them!)
This experiment was with width="xx%".  Trying various options for
height="xx%" only seemed to confuse the browsers.
 
Now, can anyone tell me if XHTML is so limited?
