flagging <table> as "layout" in v10

[anionic]

v9 encouraged me to include the word "layout" in the summary attribute of any non-data table to suppress inappropriate msgs, so I did and it did. But v10 is warning about missing <th> elements in these tables and says

If this is a layout table, then include "layout" as part of the table's "id" attribute value and this message will not be displayed.

I really don't want to do this (it could break CSS and scripts) and wonder whether I can configure Validator to behave as before?

Hello,

For layout/non-data tables, it is best (more proper) to not use the "summary" attribute or set it to an empty string, that is why this has changed in V10.

I could probably turn this message off if "layout" is used in the summary attribute, like in it was turned off in v9, but v10 won't recommend that approach anymore. Does this sound good?

UPDATE: The next V10 update should assume tables with "layout" in the "summary" attribute value are layout tables and will suppress the warning about missing header cells, however, this warning message may be generated (which can be disabled if desired):
This appears to be a layout table. If so, then the "summary" attribute should not be used or its value should be empty. Visit http://www.w3.org/TR/WCAG20-TECHS/H73 for more information.
