delimit cells across the row. Thus, the problem is with the row that has E: ((Para | Figure | MediaObject | Table)*, Section1*) in the first column, Body in the second column, and nothing in the third row.
Second, the purpose of the E: prefix is to identify a single name as an element tag and not a paragraph tag, character tag, or table tag. E: is always optional. It cannot be used to identify an expression. Remove it in the erroneous line and you should be OK.
