Good point. I think there are no constraints regarding that in the DTD 
(and I guess this is not even possible to constraint in DTDs...). In 
XHTML 1.1 module "table" DTD [1] the TD and TH are treated in an equal 
manner (<!ENTITY % tr.content  "( %th.qname; | %td.qname; )+" >).

We should not contraint their use also, but maybe make some meaningful 
"Layout's" (e.g. "first row header", "first row + first column headers", 
etc) to make displaying of CSV-data more easy to achieve.

Cheers,
Ernesto
