Example WCAG 2.0 Technique

From H73: Using the summary attribute of the table element to give an overview of data tables:

For each data table:

1. Check if a summary attribute is present for the table element.
2. If a summary is present, check that the summary attribute describes the table's organization or explains how to use the table.
3. Check if a caption element is present in the table element.
4. If both a summary attribute and a caption element are present, check that the summary does not duplicate the caption.
