Valid Elements for Element Groups

The following table specifies the elements that each element group can contain. If an element is not listed in the "Can Contain Elements" column, its presence within that element group is a constraint violation. For example, if an os_list_item is added to an os_table , this is a constraint violation. According to the table below, the element group os_table (listed in the first column) can only contain the element os_table_row , which is listed in the second column of the table.
