MathML 3.0: W3C Recommendation

When writing a MathML expression, you should group elements within an <mrow> in the same way as they are grouped in the mathematical interpretation of the expression. Proper grouping helps the rendering of the expression in several ways:

It can improve the display by possibly affecting spacing.
It allows for more intelligent line-breaking and indentation.
It simplifies the interpretation of the expression by automated systems such as computer algebra systems and audio renderers.
