I put this together very quickly before the team C meeting to help
discussion.
At the face 2 face there was discussion about 1.3.1, 1.3.2 and 1.3.4 and
there was agreement to investigate combining 1.3.4 with 1.3.1.
I've looked at 1.3.1 and 1.3.4 and the how to meet documents for them. I
think we can just eliminate 1.3.4 as it is less restrictive than 1.3.1
because 1.3.1 requires that the information conveyed through presentation
can be programmatically determined while 1.3.4 just requires that the
variations in presentation of text can be programmatically determined OR
the information is available in text. The only thing that 1.3.4 is
providing is the option to provide the information in text but is still
not requiring it. I also think that the definition of presentation that
is used in 1.3.1 will cover variations in presentation of text. But, I
wasn't at that part of the face to face so I'm sure I have missed
something. But, to get the discussion started I'll take a stab at the
modifications we need to the 1.3.1 HTM document in order to incorporate
the information from 1.3.4.
Add another example in the second paragraph of the Intent section of HTM
1.3.1:
indicating that some words that have special status by changing the font
family and /or bolding, italicizing, or underlining them
Add G117: Using text to convey information that is conveyed by variations
in presentation of text to the list of sufficient techniques for 1.3.1
I struggle with what to do with H49: Using semantic markup to mark
emphasized or special text (HTML) This was only sufficient to meet 1.3.4
and I don't believe that it meets 1.3.1 since the in some examples
information is not conveyed, just the presentation. Yes, <em>, <strong>,
etc do convey some structure but they just convey that the data has that
structure - not why thus, I'm not sure it is conveying the information as
required by 1.3.1 I'm surprised that G115: Using semantic elements to
mark up structure which is sufficient to meet 1.3.1 is a general
technique since it provides HTML examples. I think we need consider
eliminating the examples that related specifically to text and truly only
use semantic elements to mark up structure. Some of the examples in H49
(such as the ever controversial quote, and blockquote do convey meaning.
And, super and subscripts do convey meaning about how letters are
organized so perhaps we need to combine H49 and G115. What do people
think? I think that the troublesome elements are em and strong since they
do convey meaning but not necessarily meaning. But I'm not sure how we
can say that some semantic elements are acceptable to convey information
and not others?
If we believe that H49 is valid for 1.3.1 than F2: Failure of SC 1.3.1
and 1.3.4 due to using CSS to create variations in presentation of text
that conveys information without also using the appropriate markup or text
could be added to 1.3.1 as well.
I think the benefits section of 1.3.1 covers the general benefits of
structural markup and that we do not need to add the specific benefits
from 1.3.4. It might be possible to incorporate the two bullets from
1.3.4 into an example type sentence at the end of the 1.3.1 benefits
section if people feel it is necessary.
I'm not sure how the example in the HTM of 1.3.4 applies and do not
suggest moving it to 1.3.1. But, we should discuss with Makoto and
Loretta first as I believe they were involved in the creation of this
example.
How would this combination affect the open issues?
588 - wants to promote 1.3.4 to level 1 - this combination essentially
does that. The proposed response already addresses the comments about
1.3.2.
583 - wants the meaning conveyed so I think combining with 1.3.1 and
requiring the information to be conveyed would resolve this issue.
1284 - wants this SC strengthened so I think combining with 1.3.1 would
resolve.
1234 - wants some L2 SC of 1.3.1 moved up to level 1 - I'm not sure if the
SC in question is 1.3.4 or 1.3.5 - we should contact the commenter for
clarification.
964 - wants to add example about highlighting to 1.3.4. I don't think that
would be appropriate for 1.3.1 so propose a reject of this one.
863 - needs more thought
715 - wants 1.3.4 strengthened, I think combining with 1.3.1 would resolve
636 - wants 1.3.4 strengthened ( I think) needs a second look
