The World Wide Web Consortium (W3C) has released the Mathematical Markup Language (MathML) 2.0 as a W3C Recommendation.
MathML 2.0, an XML application, provides encoding mathematical notation and content for use on the web.
W3C has also released the Canonical XML 1.0 Recommendation. This specification defines a method for serialising XML documents that eliminates incidental variances in their syntax as permitted by XML 1.0. This strengthens XML's ability to deliver secure digital signatures.
