Hi dev,
For Dutch Web Guidelines validity a<th> have to contains scope
attribute (scope="col" or scope="row") which means that default wiki
tables are invalid currently.
See
http://www.w3.org/TR/xhtml2/mod-tables.html#non-visual-rendering
for example of scope attribute use.
I propose to modify XHTML renderer table header cell to do the following:
* if a scope is explicitly provided reuse it
* if there is no scope:
** if first line or not first column:<th scope="col">
** if not first line and first column:<th scope="row">
I thing that covers most of the use cases and it will avoid having to
set explicitly scope attribute in all our standard pages.
WDYT ?
