I tested the page with Amaya release 2.1 running on Linux 2.2 (RedHat 6.1 and
Gnome) and got nothing rendered each time (in the alternate view). I got the
same results running Lynx 2.8 on linux as were on windows. Netscape 4.6 in
linux gave me the same as your results for MSIE
I agree that the behaviour does not seem completely specified for alt="" or
alt=" ". Actually, why not use an object element instead (or use XHTML and
namespaces to include SVG...)

using "" versus " " has been argued back and forth. It is my
interpretation of sifting through the archives that if the "desired effect"
is a space between two characters, using an image for this is
inappropriate. We suggest style sheets.
Also, some people have favored "" while others like " ". Most of the
arguments have been based on the current state of the art handling of
spaces. However, it appears that "" and " " are currently handled the same
[http://www.w3.org/WAI/GL/tests/spaces.html]. I was the only one to
respond to the tests, so it only includes the 3 browsers I was able to test.
Many people pointed to the HTML4 spec where it says that "leading or
trailing spaces" may be ignored. However, is a single space trailing or
leading?
is inappropriate since it is intended to be used as a typesetting
hint as Nir described on 17 November:
http://lists.w3.org/Archives/Public/w3c-wai-gl/1999OctDec/0070.html
Alan Flavell also makes a good point about nbsp not being considered "white
space" http://lists.w3.org/Archives/Public/w3c-wai-gl/1999OctDec/0069.html
Therefore, I don't think it matters much if we suggest that people use ""
or " ". Personally, it seems to be a matter of author preference. Neither
one is going to cause horrible things to happen (although "" has
historically - i.e. it supposedly used to be ignored by Lynx but doesn't
seem to be anymore).
If we look at the long term, I would suggest using a space since spaces are
supposed to be preserved in XML. However, I also agree that it is a matter
of separating content from presentation. A space seems to say, "there is
formatting going on here" while null says, "it's decorative."
Again, I think it boils down to author preference.
