I understand your approach but there is an issue with this.

In an home made tool it is perfectly possible to do as you recommend.  
Though it makes it difficult if you want to keep the markup validity  
of your document like processing them with xslt. In a tool which has  
been made to be conformant, and will not let use the alternative to be  
non conformant, that will become a major hurdle.

There are different levels of conformances

* Markup conformance
* Accessibility conformance

With a mandatory "alt" attribute, my only reasonable solution  (in the  
case of a personal usage) is something along:

	<img src="boo" alt=""/>

which is fine (for me). It has other consequences when you come to  
switch from private to public. The tool will not notice if the alt is  
here on purpose (decorative image) or not.

/me is trying to find a solution which is not perfect but acceptable  
for everyone making compromises.
