The Math Working Group has published two updated W3C Recommendations:
- XML Entity Definitions for Characters (2nd Edition). This document defines several sets of names, so that to each name is assigned a Unicode character or sequence of characters. Each of these sets is expressed as a file of XML entity declarations.
- Mathematical Markup Language (MathML) Version 3.0 2nd Edition. This specification defines the Mathematical Markup Language, or MathML. See the separate appendix in the document for the list of changes.
