Hi Gregg

 

Are we sure that the optional techniques are *never* sufficient? I think the
proposed wording still throws a negative spin on the optional section. I
think I understand what you are getting at, that we don't want people
claiming conformance by throwing a couple of optional techniques onto their
web site and avoiding the sufficient techniques. But I am concerned that the
negative spin (i.e., "not sufficient", and "not required") will turn the
optional techniques section into a boneyard. In some cases there are some
awesome techniques in there (such as 2.1 "using unique letter combinations
in drop down lists") that I would hate to see shelved. And there actually
may be rare occasions when an optional technique may be perfectly sufficient
to satisfy the SC. I don't think we can rule that out given that the "how to
meet." doc is non-normative, and that the important thing is that they meet
the SC, not that they are forced to use specific techniques.

 

How about this, as a middle ground? I think the words "optional,"
"advisory," "additional" and "supplements" below make it clear that they are
the optional techniques are *not* intended by the working group to be
replacements for the sufficient techniques. 

 

<proposed>

Optional Techniques (Advisory) for 2.3.1

The following techniques are provided to supplement the sufficient
techniques, and may enhance accessibility.  Not all of these techniques can
be used in all cases. However, some of them may be effective in some
situations and for some types of users.</proposed>

Hi David,

 

 

RE Validation:

Please check the latest draft.  A couple meetings ago we moved validation
from advisory to sufficient.

 

RE the other comment:

I think that you are correct.  By saying that optional are not required it
raised the question about the others being required.  We will have to fix
this.   

 

Because they are listed just below the Sufficient - we do have to do
something to make sure that it is clear they are different than the
sufficient techniques.

 

Hmmmm

 

How about

 

<proposed>The following additional techniques are not sufficient for meeting
this success criterion but should be considered as additional ways to make
content more accessible than specifically required by the success criterion.
Not all of these techniques can be used in all cases. However, some of them
may be very effective in some situations and for some types of
users.</proposed>

All of the advisory sections of the "How to meet." doc say:

 "Although *not required* for conformance, the following additional
techniques should be considered." 

By saying the advisory techniques are "not required," are we not implying
that the core techniques are "required"? It seems to imply a requirement of
the core techniques.

The other problem is that some of the solutions in the advisory sections are
very useful and we are almost deterring people with the current language. I
think this is particularly evident in the 4.1 advisory section where we find
"Validation" as an optional technique. We are almost discouraging people
with our current language. Another place it strikes me as deterring an
extremely useful technique is in the 2.1 advisory to use unique letter
combinations in drop down lists. 

There actually may be cases where someone can meet the SC by using some of
the optional techniques, and we don't want to imply that that is not
possible. I think we need to reword this. I recommend the following:

<current>Although not required for conformance, the following additional
techniques should be considered in order to make content more accessible.
Not all techniques can be used or would be effective in all
situations.</current>

<proposed>The following additional techniques should also be considered as
ways to make content more accessible. Not all of these techniques can be
used in all cases. However, some of them may be effective in some
situations.</proposed>
