The new technique looks good to me. I've included here a few things that I noted as I read it: A pedantic suggestion for the Description section is to make the description of tabular data more clear regarding the type of logical relationship. In particular, that the relationships have two dimensions. Perhaps the following could be incorporated: "Tabular data is information that has a two-dimensional relationship; meaning the data has relationships in both the horizontal and vertical directions." Also in the Description section: change "Techniques such as inserting tabs between columns..." to "Techniques such as inserting tabs to create columns...". That is, use "create" for clarity that the tabs create the columns, otherwise is sounds like they already exist and tabs are just inserted in between them. An extra closing bracket is at the start of the last sentence in the Example 1 text.

(This technique has been renamed "Using table markup to present tabular information" and the technique has been combined with the technique about "Using the th element to identify column and row headers." The technique about using the th element no longer exists as an independent technique.) After careful review of the HTML 4.01 specification, we decided not to use the scope attribute because it is not required by the specification. Screen readers are able to correctly identify column and row headers in simple data tables when only the <th> element is used. An algorithm for recognizing heading information in the absence of the scope and headers attributes is described in the HTML specification. The revised technique, Using table markup to present tabular information, is available at the technique, http://trace.wisc.edu/wcag_wiki/index.php?title=Using_table_markup_to_pr esent_tabular_information A new HTML technique has also been added to address use of the scope attribute: Using the scope attribute to associate header cells and data cells in data tables Is available at http://trace.wisc.edu/wcag_wiki/index.php?title=Using_the_scope_attribut e_to_associate_header_cells_and_data_cells_in_data_tables Please review these techniques and let me know if they address your concerns. Thanks so much. John "Good design is accessible design."
