MathML 2 reference with examples

Both the indexes and the examples were extracted from the MathML2 Proposed Recommendation and MathML 2 DTD. . The reference will be upgraded when the standard is finalized. The examples were extracted programatically, so there can be some problems introduced during processing. This reference is an upgrade of the older Candidate Recomendation Reference, which can be still downloadad as a zip or tar archive. Main features: * Clickable indexes (including graphic index) * Click on "Go to standard" leads to the relevant part of the specification * Relevant MathML code is available for direct download or inside XHTML code for browser testing.
