The MathML2 Recommendation included MathML Document Object Model Bindings for IDL, Java, and ECMAScript. These were available separately from the URLs http://www.w3.org/TR/2001/REC-MathML2-20010221/mathml-dom.idl for the IDL bindings and http://www.w3.org/TR/2001/REC-MathML2-20010221/mathml-dom_java.zip for the zipped Java bindings.
Versions of these bindings which reflect corrections and changes since the MathML2 Recommendation are now available at the following URLs:
Also available is an updated version of Appendix D of the Recommendation.
These will be gradually updated as needed to reflect further corrections and changes.
