tgroup

The <tgroup> element in a table contains column, row, spanning, header, and the body (<tbody>) of the table.

Deleted " and footer specifications", since DITA uses the OASIS interchange model, which doesn't include tfoot.

These models represent only the default document types distributed by OASIS. Actual content models will differ with each new document type.
