You're right about the authoritativness of comments in DTDs: 
"Comments appearing in the HTML 4 DTD have no normative value; they 
are informative only." (http://www.w3.org/TR/html401/conform.html#h-4.2).
However, the sections "11.4.2 Categorizing cells" 
(http://www.w3.org/TR/html401/struct/tables.html#multi-dimension) and 
"11.4.1 Associating header information with data cells" 
(http://www.w3.org/TR/html401/struct/tables.html#header-data) are 
also about scope and table header cells. My understanding is that 
when you use the SCOPE attribute on a TD element, you indicate that 
you want this to be a header cell.
