An interesting proposition.

I certainly think that talking about "the alt attribute" instead of 
talking about text alternatives in case the imagery isn't clear has 
been a mistake. Not least because the alt attribute is limited to the 
img element, and isn't what is generally considered the best way to 
provide for alternative text - SVG uses child elements instead which 
can bring a few advantages and is more like what the XML accessibility 
guidelines suggest. HTML provides alt, title, longdesc, and the fact 
that images can be explained in accompanying text (this is something 
that is particularly good in print and I wish was done better and more 
often).

cheers
