Hi All
Here in Ontario our Government has enacted a law at www.aoda.ca and
one of the standards is for web accessibility. It has come to my
attention that the powers that be are considering making WCAG 2.0
level A as the benchmark. This would be a big mistake so I am looking
for any information that I can present in opposition to this
consideration. If anyone can help it would be greatly appreciated.

I'm assuming by your questioning that WCAG 2.0 level A will cover
accessibility for all disabilities. So I ask you is level A
sufficient? If not, then which disabilities are expendable?
It has been my understanding that level AA is the benchmark, is this
not correct?

Geoff,
You're making a big assumption I think. I'm not suggesting anything in my question and am certainly not going to detail that any disabilities are "expendable".
You seemed to state that you didn't think that WCAG 2.0 was appropriate and I wanted to hear your thoughts on why. Now it sounds like your concern is whether it is WCAG 2.0 A or AA - is that correct? I'm still interested in your thoughts on this.
Thanks,
AWK

Geof,
Here is why I like WCAG 2.0 Level A. It is
sufficient to cover US 508 at an equally effective
access level. Please feel free to check my work.

Geof,
I would suggest that the AA compliance level would be the desired level.
Currently the Canadian Federal Government mandate AA (or Priority 1 and
Priority 2 checkpoints) of WCAG1
(http://www.tbs-sct.gc.ca/clf2-nsi2/clfs-nnsi/clfs-nnsi-2-eng.asp#cn_1_cww
), and the AA WCAG2 level closely maps to the level of effort required
(for lack of a better term) to reach compliance. Countries such as New
Zealand that have adopted WCAG2 as their Standard with compliance to AA
are existing precedent that it is viable and achievable for government
institutions to meet. (http://bit.ly/8Ct6wR)
WCAG2 A compliance is more closely associated to Section 508 compliance;
most governmental entities in Canada (and elsewhere) currently have
existing higher standard requirements, usually resulting in AA compliance
requirements to either the older WCAG1 or the newer WCAG2.
Hope this helps.

Hi Geof
I think your original phrasing of question has created some confusion. As I
understand it you are not anti-accessibility (as your question seemed to
suggest) at all, but simply that you don't think single-A conformance is
sufficient.
To be honest I'd have to agree with you. I've worked with many Government
departments in the UK and Australia, both of whom have much more stringent
accessibility requirements than many other countries and AA conformance was
seen as the sensible minimum standard.
I say minimum standard, as many people seem to forget that you can aim
higher...there is nothing stopping you.
The reason I think AA is the best balance is that it is a) very easily
achievable and b) covers a broad range of disabilities. As soon as you try
to hit full AAA compliance the difficulty rating hikes considerably and the
number of additional people it caters for diminishes so whether you are
looking at it in business terms (of return on investment) or Government
terms (of sound public spending) there are significantly diminishing reasons
for doing so. Again, I'm not saying there are no reasons so please do not
take my comments as anti-AAA conformance - I just live in the real world.
Most of the clients I have worked for I have actually convinced to go a step
further than AA, but without actually aiming for full AAA compliance. There
are many requirements of the AAA level which are actually easy to meet
whilst adding very little to development costs, and sometimes nothing to the
running costs of a website.
Sadly here in Ireland many Government bodies barely pay lip-service to the
matter of accessibility and even An Garda Síochána (the national police
force) recently relaunched their website which fails miserably to address
the issue. Thankfully the National Disability Authority is working to turn
that around.
With regards to the new legislation in Ontario I would not be anti-single-A
conformance at all. It is usually necessary to do these things in stages (a
bit like transitional/strict DTD for HTML...it's 'transitional' for a reason
people!) whereby a simple standard is adopted with an aim towards working
towards a higher standard over time. For example the UK Government set out
a plan (not yet fully successful) for all Government site to be single A
accessible first, with a deadline for AA conformance a while later. They
even threatened to pull budgets for any new/revisted website that does not
conform to AA though this proved a little bit of a toothless threat.
If your "powers that be" issue a consultation request, please post a link up
here as I'm sure that quite a few people here would be happy to contribute.
You might also want to post it on the Web Accessibility Group (
http://www.linkedin.com/groups?gid=41800) on LinkedIn if you are a member.

After rereading my post I see why now the confusion, it was only
meant to be A not AA.

Hi Andrew
Sorry if there was any confusion that was exactly what I meant and I
agree wholeheartedly with your opinion.
Our standard in its rough draft also set out deadlines for meeting A
and AA which is acceptable if there is some sort of enforcement
mechanism, however that in itself appears to be toothless at present.
I believe public consultation is either already posted or will be
coming up, will look into it.

A stepped model would be best, but enforcement is
the problem. Any time you can get one step
instead of 2, you're better off.
An extremely practical model is this. You can
push for all sites created after 20XX to be in
Level A. After 20YY new sites should be Level AA.
If the early ones don't get converted it is
probably not serious, Level A is a very strong
508. Moreover, most sites don't live long enough
to avoid the ultimate conversion to Level AA.

Hi All
Just used another online accessibility checker that gave me the
following error:
* Each ul or ol element that precedes the last h1 element and
appears to be a navigation bar should be immediately preceded by a
heading element, preferably an h2.
* Warn: 2 ul or ol elements (out of 2 total) do not meet the criteria.
* Each map element that precedes the last h1 element and appears
to be a navigation bar should be immediately preceded by a heading
element, preferably an h2
Is this correct?
cheers

No. It's silly to expect or require that all things that might
possibly be, look like, or even actually are navigation elements be
proceeded by a heading. How many sites do you know of that have a
"Navigation" heading immediately before the main navigation links?
It's reasonable to assume that both sighted and non-sighted users will
understand that a group of links near the beginning of the page that
link to major areas of the site are probably the navigation.
Suggesting that developers must explicitly tell the user what they are
via a heading is a bit extreme.
Now if the group of navigation items already has a visible header,
then yes, that header should be marked up as a header at the
appropriate level.
Additionally, adding the ARIA role="navigation" allows assistive
technology to explicitly know the section of the page that is
navigation.

Thanks Jared, just what I thought. I have the Landmarks there but it
didn't detect them and if I were to put headings it would throw off
my whole design

That is one interpretation (FAE evaluator correct?). You will not find
explicit language like that in the WCAG 2 spec however...
FWIW, I disagree with that interpretation, and have said so publicly
before.

Same here...it's opinion codified in a validator (I've said the same about
what Frauenhofen institute are doing at their end with regards to automated
WCAG 2 validation...I'd go as far as saying that, by its very nature, you
can't automatically test for WCAG 2)

Coding opinions in tools or evaluation methodologies is unfortunately
another aspect of standards fragmentation that contributes to confusion
and slows down the overall implementation of web accessibility.
Note, however, that you couldn't test *for* WCAG 1 either but you can
test for the existence of some known issues. For instance, in WCAG 2
some of the Failure Techniques are automatable. I think tool producers
can benefit from this structure in WCAG 2 and from the opportunity to
contribute additional (Failure) Techniques to the WCAG Working Group.
Best,
Shadi
