(just two quick points)

1. Your example uses grid-col for cells/compartments, not columns.

Shouldn't your grid-col be named grid-cell?

eg

<!ELEMENT grid  (grid-row*)
<!ELEMENT grid-row  (grid-cell*)>
<!ELEMENT grid-cell  %some_permissive_content_model;>

or

<!ELEMENT grid  (grid-row*|grid-col*)
<!ELEMENT grid-row  (grid-cell*)>
<!ELEMENT grid-col  (grid-cell*)>
<!ELEMENT grid-cell  %some_permissive_content_model;>

2. Why allow rect, but not circle and ellipse?

A grid-cell might share the content model with g, for example.
