In section 3.2.5.8.2 "Vertical Stretching Rules", it is indicated that 
∑ and ∫ stretch vertically by default:

"Most common opening and closing fences are defined in the operator 
dictionary to stretch by default; and they stretch vertically. Also, 
operators such as ∑, ∫, /, and vertical arrows stretch 
vertically by default."

However, the operator dictionary does not define these symbols as 
stretchy. Hence I suggest to remove from chapter 3 the requirement that 
sum and int stretch vertically.
