I took an SVG  XML picture (it actually was a painting in SVG, not just
lines and simple shapes) - 100K, and converted it to a GIF - 80K.  Not much
difference, really!  And if the XML file is compressed in transmission, it
would probably be even smaller than to send than the GIF (since the GIF
probably won't compress much more).  I also took a 2-column Word97
document - 63.5K - and opened it with Abiword (www.abisource.com) then saved
it.  Abiword uses an XML file format as its native format.  Abiword XML file
size: 48.8K.

These results support Elliotte's post.
