ISSUE-57: [dup of 20] @headers

[dup] headers

[dup of 20] @headers

State:
CLOSED
Product:
HTML 5 spec
Raised by:
Joshue O Connor
Opened on:
2008-07-17
Description:
The current wording for the headers attribute only allows the space separated token values to reference the id attribute of a header cell(th). It states

"The headers attribute, if specified, must contain a string consisting of an unordered set of unique space-separated tokens, each of which must have the value of an ID of a th element ..."

As hierarchical headers are not allowed in HTML5, this means that conceptual headers (cells that contain data and have their own header,but act as a header for other cells in the table) must be marked up as a td. As these cells are conceptually headings, the headers attribute should be able to reference the id attribute of these cells.

Related notes:

It is worth noting that ISSUE-20 and ISSUE-57 have considerable overlap.. you may need to bounce around between these two issue's mailing list discussion to get a complete picture.
