Subject: Table accessibility proposal
One of feature requests which DocBook TC is solving right now is table accessibility. One requirement for accessibility on tables is ability to mark cells that contain headers for column or row. Column headers are marked by thead element in CALS table model. However CALS table model doesn't provide means to mark some cell as row header. On its last telecon DocBook TC (http://lists.oasis-open.org/archives/docbook-tc/200411/msg00008.html) proposed following solution (taken from DITA DTD) to this issue: Add rowheader attribute to the table element. This attribute can indicate either that first column of table contains row headers (value "firstcol"), or that there are no row headers in a table (value "norowheader"). <!ATTLIST table rowheader (firstcol | norowheader) #IMPLIED> Processing tools can use this information to create more accessible output (e.g. decorate table cells with scope and/or header attributes in the case of HTML output). Any comments or suggestions to this proposal? Is this mechanism sufficient for your table accessibility requirements?
