This does not work because the close tag is required according to the
spec (like a script tag).
From a quick read on the interwebs, yes, it seems that <object> is an
html4 specification. One problem with your solution, is that <object>
does not allow an 'alt' attribute
The problem w/ <img src='foo.svg"/> according to my reading, is that
it is not officially supported, and is only incidentally supported by
the browsers (but, as you can see, without svg interactivity).
I thing the solution is to use an <object> tag for svg, but an <img>
tag for the rest. It might also make sense to just inline the svg?
see:

for an interesting writeup on the issues.
