           Summary: Generated content must be accessible
           Product: HTML WG
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: a11y
          Severity: normal
          Priority: P2
         Component: HTML5 spec (editor: Ian Hickson)

        ReportedBy: gcl-0039@access-research.org

The HTML5 spec should clarify that generated content should be included in the
DOM, available to assistive technology, and copied to the clipboard along with
other content. This applies to content styles add before or after elements
(e.g. content: "Note: ") as well as numbers and bullet characters inserted
before li elements, etc.

Current browsers vary in their handling of this, causing problems for some

Use case: Nadia's screen reader is reading her a document, but it doesn't make
sense because the browser does not expose generated content, and thus the
screen reader cannot detect or voice the explanatory text such as "Example:",
"Note:", and "Warning:" added before the paragraphs.

Use case: Ralph has difficulty entering text, so he relies on copy and paste
more than most users. However, when he selects and copies a web page includes
lots of numbered list items, then pastes it into email, all the item numbers
are replaced by hash signs. Because editing the text is difficult for Ralph, it
is much more of a problem for him than for other users who can correct the
errors more easily.

Note that it should still be possible to distinguish generated content from
author-supplied content. 

I apologize if this is not the specific spec where this should be addressed,
but it must be addressed somewhere.
