I think Alexey's point is that in a correctly authored page no alt
attribute could perfectly reasonably mean the attribute is empty, this
is a good argument, but one that falls down in reality because so few
pages are correctly authored so those groups needing good ALT are left
at a disservice unless authors co-operate by specifically giving ALT
an empty value.
