Yet you use Transitional rather than Strict?

That is a somewhat narrow view to take I think. There are other
browsers.

Do you mean alt attribute?

On spacers: Use CSS and margins/padding instead.

On bandwidth: 6 bytes per image, and rather less with gzip compression

On time: It doesn't take very long to type 6 characters, and less if
you use software which inserts it automatically for you.

So you've never used Lynx then? In the absence of explicitly
alternative content, it falls back to the image filename. I don't know
what JAWS and other screen readers do.

This, however, is not a validation issue. It is an issue with the
design of the HTML language. You might want to try the www-html-editor
mailing list, but I doubt you will find much willingness to change the
language on that point.
