 Hello Steve,
 That's right. HTML5 will also fail the use of summary
 attribute on these table. Or the use of an id attribute on a
 TD element that is referenced by the headers
 attribute   from a data cell in the first
 table on the page that uses headers-id method.
 But this remedial technique is not suggested for HTML5.
 That example file is valid with
 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
 I'd like to see a valid technical  / accessibility /
 usability   or other reasoning against this
 Thanks and regards,

  Hi all, note I don't
  think this use of Hx elements is appropriate (in HTML5) at
  least as a heading implies a new section [1]

  Refer to table#2 on this page:
  Well if one is arrowing down a column # 2or subsequent
  column, the screen reader does announce the group header
  because it is a TH cell./ (this is in response to Josh's
  question during the call).
  Use of h<n> tags in a data table is valid code, it
  exposes structure of the grouping within the table, allows
  users to jump to the section of interest and then navigate
  the table and have only row header  to its left and
  headers announced. This reduces verbosity. Yet one can
  JAWS+T and have nearest heading announced ... a technique
  that is accepted for determining context of a link. So one
  can use the same technique to understand  context in
  of group headers. (Only JAWS  supports H80)
  Also one navigates a page and determines structure by
  multiple methods: landmarks, headings, tables, lists,
  etc. and not just heading navigation. So if this method is
  used to code complex tables, users will be able to figure
  that out.
  Also a single level of headings (styled as needed)
  be used in the table ... the method may not be appropriate
  if one needs to use more than one level of headings.
  It is a non "standard" method that is valid code
  and AT supported.
  I believe it is an alternative technique to headers-id
  one chooses not to use headers-id for whatever reason.
  Thanks and regards,
  Sailesh Panchang
