entrytbl does not equate to nesting tables as is allowed by HTML and
XSL.

entrytbl is effectively a table cell that is divided up into rows and
columns of table cells, and only table cells.  HTML and XSL let you
put blocks of text, images, and other stuff in the same table cell as
a true nested table (or multiple nested tables).

True nested tables are useful.  Subdivided table cells as provided by
entrytbl are only halfway useful at best.  entrytbl alone is not a
good enough reason to continue to support the full CALS table model.
