    +

    A comment contains content expressing reaction to other content.

    +

    Comments can annotate any visible content, from small spans of text, to other comments, to entire articles. Authors SHOULD identify the relationships between comments and the commented content, as follows:

    +
      +
    1. If the comment is a reply to another comment: +
        +
      • If all ancestor comments are available in the DOM, make each reply comment a semantic descendant of the comment to which it is replying, either by making it a DOM descendant element or by using aria-owns.
        • +
      • Alternatively, if all ancestor comments are not in the DOM, such as when comments are paginated, the hierarchical + level MAY be indicated via aria-level. Additional group positional information MAY be indicated via aria-posinset and aria-setsize.
        • +
      +
      2. +
    2. Otherwise, if the comment relates to other content in the page: +
        +
      • Provide aria-details on the element containing the commented content with a value refering to the element with role comment.
        • +
      • If there are multiple comments related to the same commented content, either provide a value for aria-details on the commented content that refers to each individual comment, or use aria-details to refer to a parent container of the comments. If aria-details refers to an element containing comments rather than comment elements, authors SHOULD assign a role of group or region to the referenced container.
        • +
      +
      3. +
    +

    If the author has not explicitly declared aria-level, aria-posinset, or aria-setsize for a comment element, user agents MUST automatically compute the missing values and expose them to assistive technologies.
