7// 22.1.2.51
8// jc (Justification)
9// This element specifies justification of the math paragraph (a series of adjacent instances of mathematical text
10// within the same paragraph). A math paragraph can be Left Justified, Right Justified, Centered, or Centered as
11// Group. If this element is omitted, the math paragraph is Centered as Group. Whether the element is absent or
12// present without the val attribute, the default of the val attribute is centerGroup . This means that the instances
13// of mathematical text can be aligned with respect to each other, but the entire group of mathematical text is
14// centered as a whole.
