Well, first, it's not a given.  You have yet to prove to me that it was a
given that you could not supply an alternative text to your image of that
building in Boston.  You simply stated that the effort could not be
justified by you: "...the single constrain I have: not finding it necessary
to provide replacement text for all those images. This would take too much
time for little benefit."  There is no technical justification, only a
personal perspective - *you* did not find it necessary, and *you* felt that
it would take too much time.

Neither is good, but alt="" indicates that the value is null.  How will the
user agent do this analyzing you speak of, and why could it not also analyze
an image with alt=""?

Perhaps, but to date none has been proposed.

That's a might big "given".  And so, "for conformance sake" an image can
exist without an alt attribute?  You are simply replacing one bad solution
with another bad solution - but your bad solution makes it easier to be "in
conformance".  It's a shell game. You upload your image of the building in
Boston, and you're "done with it".  How does this help anyone besides you?

I am not ignoring it.  I just responded above, and I will again go on record
as stating that neither solution is good; both are wrong, but having a spec
that pardons and condones a state that will *directly* have a negative
impact on accessibility is "wronger". I say directly because the draft spec
allows, pardons and permits pages to have images with no alternative text:
it allows the page to remain in conformance while at the same time
deliberately excluding at least one user-group.

I have seen absolutely nothing that shows how alt="" can be *worse* than
having no alt attribute at all, and we have plenty of "cowpath" evidence
today that shows that current technology prefers alt="" over no alt
attribute.  Yet this has never been acknowledged either.

...and so the answer is to permit bad behaviour, "harmful" behavior, and
allow a document to none-the-less be "conforming"?  This is not a solution,
it's a Get-Out-Of-Jail-Free card
[http://www.aim.org/images/get_out_of_jail.gif].

First of all, who exactly has stated that the current poor solution of
alt="" is a problem?  It's less than ideal, no argument, and it does nothing
for accessibility, but problem?  State the problem:

Images without alternative text are inaccessible to non-visual UA's and
users of those UA's.

OK, that's a problem.  How does allowing an image to exist in a page without
an alternative text solve the problem?  Oh, it makes it easier to be in
conformance, it makes it easier on the author who cannot justify the effort
required, and it makes it easier for the Flickr's of the world, but *HOW
DOES IT SOLVE THE PROBLEM*?  The image is still inaccessible to that end
user.

What is the harm you reference?  I know first hand that currently, images
with alt="" are not voiced by screen reading technology; where-as images
without any alt attribute are generally voiced with the file information
"image: DC27456 dot jaypeg".  Which is less harmful?  Therefore, from what I
know first hand currently the best solution is alt="".

A realistic spec?  One that references a lead-to-gold promise of heuristic
image analysis?  Anne, please.  Apples to apples and oranges to oranges.
You state that authoring tools will never evolve to solve the problem, but
some magical future tool will emerge to provide a better result?  Now I'm
the one having a hard time buying in.

No, I cannot, and have never presumed nor stated such.  This is why I can
accept that even alt="photo of a building" is better than "image: zero zero
nine dot jaypeg" [http://anne.is.weggeweest.nl/2006/boston/009.jpg] -
because for some users that *might* be sufficient.  I don't know, and do not
want to presume either way.

1)  I used emphasis to point out the issue: that in your piece you stated
that the reason for not providing an alt value was not that it was
technically impossible to do, but rather that in *your opinion* it was too
much effort for too little pay-back. 

Every time somebody strenuously debates with you guys, you claim we are
grandstanding or being argumentative and negative.  The written word is a
difficult medium to express nuance, and so I must use imperfect means of
applying emphasis.  

And so, without all caps:  Anne, the point that *I* am making is that you
used a loophole in the draft spec to avoid adding alternative text - it was
simply easier for you to upload the photo of the building in Boston and move
on - no problem, my page is conformant (problem solved). This is wrong, and
if you can (and did) do it, then multitudes of others after you will do the
same, and accessibility will be the whipping post.  In my opinion, there is
nothing that can justify this - nothing!  That it will continue to happen I
must accept - that it is "permissible" by virtue of an international
standards document I cannot.  And *that* is the crux of the argument.

2)  I am not saying that *you* are a poor workman, but rather countering the
proposed solution that presumes it's a strictly technological issue - and
one that can be solved by technology, by stating an old-country expression
that says that "it is a poor workman who blames his tools":

	http://www.spectacle.org/496/tool.html
"Anyone who works in software development, as I do, knows that technological
determinism is a crock.  Technological determinism is the reification of
technology. Because we love our tools, we assign them magical properties,
which simultaneously let us off the hook for our own actions. The tool has
been well analyzed as an extension of the human mind or body, but poorly
analyzed as an excuse. Blaming our technology for what we are is the moral
equivalent of the Twinkie defense."

	
http://www.wisdomworld.org/additional/KernelsOfWisdom-Series/ABadWorkmanBlam
esTools.html 
"It is seldom the case that shoddy workmanship is due to inadequate
equipment or difficult working conditions. It results, for the most part,
from the fact that the workman himself is shoddy and indifferent in his
attitude." 

(This by the way, was an expression I first learned from my British
Grandmother over a quarter century ago.  It was not meant as a slight
against you personally.)

Creating a spec that condones images without alternative text might make
life easier for indifferent content creators, it does *NOTHING* to improve
accessibility - and I have seen nothing from anyone to counter that
assertion.
