ARIA section in the specification ISSUE-109
HTML5 specification is giving details about ARIA. An issue has been opened by some WG members worried about the accuracy of this description and the possible confusion. They were asking to leave these descriptions to the original ARIA specification. As a matter of fact, HTML5 is also citing some requirements of other specifications such as CSS or HTTP. A straw poll has been issued and it has been concluded that the specification should be changed accordingly to the change proposal: “Change the title of the WAI-ARIA section of the HTML5 spec and provide advice about ARIA scope”.
Structure of HTML tables explanation ISSUE-92
There was a disagreement in the group as to the appropriateness of the example that explains the structure of HTML tables in the HTML5 specification. Some people were thinking that the example was too complex and/or changing the original nature of displaying data. After the straw poll, it has been decided to adopt the change proposal: “Move table and examples to a separate section”.
Tables and HTML layout ISSUE-130
Should table elements with a
role="presentation" be considered conforming? This issue has been focusing on this question. Tables are being used for a long time as a way to create layout on the Web. There is a majority of Web authors who want to move away from tables and accessibility document recommends to use tables only for data. Though these arguments were not decisive. It has been retained that a specification should not put the burden of change on Web authors and the solution which promotes a minimum effort for the authors is better. Following the straw poll, the decision to authorize to “use table for presentational purpose” has been made. The chairs offer tips for reopening the issue with meaningul data in the decision. Read it carefully before proposing changes.
