+mathematical meaning of its expressions in addition to the typsetting
+instructions; essentially separating style from the content of the math.  One
+advantage of keeping mathematical meaning is that conversion of LaTeX
+documents to other executable formats (such as Content MathML or Mathematica
+code) is greatly simplified.")
