Proposed Change (Be specific)
Level 1 Success Criteria for Guideline 1.1
|With new technology such as roles within the WAI, you can
assign the role of the object in a programmatically understandable way.
So if assistive technology knows the role of a picture is as a bullet,
or to say that a star means it is required, or that spacer.gif is for
spacing - why do you have to also fill in the alt tag?
||Add to the list of options: The role and behavior of non-text content can be programmatically determined|
Level 1 Success Criteria for Guideline 1.3
|T||With new technology such as roles within the WAI, you can
assign the role of the object in a programmatically understandable
way. Also you can use RDF, xfroms etc to similar affect.
||.3.2 Any information that is conveyed by color can be programmatically determined or is also visually evident without color|
Level 3 Success Criteria for Guideline 1.3
|T|| the information for the user is important not the
change in presentation...
||Information that is conveyed by variations in presentation of text is also conveyed in text, or the informations can be programmatically determined.|
||Support compatibility with current and future user agents (including assistive technologies)||T
||two questions we need to know for interface components
1, who am I ? This is a question of element integrity
a ball bouncing across the screen is the same ball and not changes of color of pixels across a screen
2, what am I? what is my function (role)
But what I am not sure is mentioned is make sure each element exists in the first place - and is not color across a screen. or letters in no logical order but that are absolutely positioned. A ball is a ball, a word is a word. Things need to know who they are and to what they belong.
|Add at level one
All objects and components that can be visual perceived can be programmatically identified thought its life cycle.
||Maybe the user needs to know what the baseline is. Then if
they really need this content they can find a user agent that can
||Add at level one
The user can access what technologies are included in the baseline, even without using baseline technologies
||1.3.1 Information and
relationships conveyed through presentation
can be programmatically
determined, and notification of changes to these is available to user
agents, including assistive
Missing hear is you need to encapsulation of the functions and behavours of each element is essential
|Add at level one
The functions and behavours of each element that can be visual Perceived can be programmatically identified thought its life cycle.
||this needs to be at level one because many sites are
completely inoperable because of failure
||move to level 1
||With RDF, XHTML roles etc, time outs can now be
||add to the bulleted list in 2.2.1 Success criteria
The role of time outs and updated regions can be programmatically determined
||With RDF, XHTML roles etc, time outs can now be programmatically determined||does the wording cover this, if not add
to the wording of 2.2.3 and 2.2.2 Success criteria
...Unless the role of time outs and updated regions can be programmatically determined
||quote" At Levels 1 and 2, WCAG conformance is only required
inside the baseline. Technologies outside the baseline need not conform,
" ah.. and then it is clarified
I do no think that is what you mean but people will misquote that to think that if they set a baseline of html, then there site is conforment because everything is in flash which is outside baseline
|change 4.2 wording
Content implemented using technologies outside of the chosen baseline satisfies all Level 1 and Level 2 requirements supported by the technologies even when accessible alternatives using technologies inside the baseline are provided
