RE: Question #2 on 4.1.1 Parsing - what it covers - markup-wise

Interesting, the predominant feeling is YES, just those 4 things.

This 4 things listed in 4.1.1 are:

1.       elements have complete start and end tags, 

2.       elements are nested according to their specifications, 

3.       elements do not contain duplicate attributes, 

4.       and any IDs are unique, 

except where the specifications allow these features.

 

Which begs the SECOND question:

 

Given the language of the SC:
4.1.1 Parsing: In content implemented using markup languages, elements have complete start and end tags, elements are nested according to their specifications, elements do not contain duplicate attributes, and any IDs are unique, except where the specifications allow these features. (Level A)

Note: Start and end tags that are missing a critical character in their formation, such as a closing angle bracket or a mismatched attribute value quotation mark are not complete.

 

Do we as a Working Group believe that 4.1.1 is ONLY applicable to content implemented using HTML/XHTML/XML as the markup languages? (and if so, why didn’t we say that?)

 

Or, would this SC cover say, SVG or ARIA, or other languages or content that is used to implement and enhance markup languages, that may also contain start and end tags, elements, attributes, attribute values and/or IDs?

(Yes, like many of you, I alsoo think about these things at midnight…….:-)

This was a carefully negotiated and precarious issue in WCAG2. Some were very vocal and very strong about requiring full validation. In the end the consensus was that we did not want Accessibility Budgets being used up chasing down ampersands (&) and trivial things that browsers and AT have overcome. We wanted accessibility budgets to only be allocated to validation issues that impacted AT, and accessibility. This was the list we came up with. Some people like the folks at WebAim would like us to consider completely removing 4.1.1. 

I personally feel that we came up with a reasonable balance with the current requirements. Maybe in an WCAG.NEXT we'll review and give WebAim an ear to present their case, and also those who would like to see more validation requirements.

Folks,

 

Do we as the Working Group consider 4.1.1 Parsing to include ONLY the 4 specific examples identified in the Success Criteria, or, do we believe that 4.1.1 Parsing to includes those 4 examples plus other things where parsing failures might affect AT?  (I know that a doctype declaration is NOT a parsing failure).

I have been at organizations where this is broader than those 4 items, and at places where those 4 sre strickly adhered to, and no other parsing issue are identified as failing 4.1.1.

 

Steve Faulkners tool and blog (https://www.paciellogroup.com/blog/2015/11/wcag-2-0-parsing-criterion-is-a-pita/) seem to support the 4 items only.
