J Changes (Non-normative)
This appendix summarizes the changes with respect to the
preceding version (1.01) of the MathML Specification.
- changes to Chapter 1 [Introduction]
- rewritten to reflect developments since publication of
the MathML 1.0 Recommendation, for example XML, XSL, CSS and schemas
- changes to Chapter 2 [MathML Fundamentals]
- rewritten to reflect developments since publication of
the MathML 1.0 Recommendation, for example XML, XSL, CSS and schemas
- examples were rewritten to reflect good MathML 2.0 practice

MathML 2.0
- changes to Chapter 3 [Presentation Markup]
- introduced a new section on bidirectional layout of
mathematics
- introduced new mathematics style attributes
mathvariant,

mathweight, and
mathcolor on token elements, and deprecated the
