The "criticism" section says that "OpenDocument is also criticized for not using the ISO 12083:1994 standard for mathematical formulae, which is not used within MathML either." First, this all reads like a criticism of MathML rather than ODF. I downloaded the spec for ISO 12083 from http://www.techstreet.com/cgi-bin/detail?product_id=52643, and found this in section 9, page 38 (12083-c.pdf) for the Mathematics DTD <!-- This DTD is included by the Book and Article DTDs of ISO12083:1994. As it is a separate entity it may also be included by other DTDs. Since there is no consensus on how to describe the semantics of formulas, it only describes their presentational or visual structure. Since, however, there is a strong need for such description (especially within the print-disabled community), it is recommended that the following declaration be added where there is a requirement for a consistent, standardized mechanism to carry semantic meanings for the SGML elements declared throughout this part of this International Standard: _ <!ENTITY % SDAMAP "SDAMAP NAME #IMPLIED" > and that the attribute represented by %SDAMAP; be made available for all elements which may require a semantic association, or, in the simpler case, be added to all elements in this DTD. --> One of the goals of MathML is to "Encode both mathematical notation and mathematical meaning." (http://www.w3.org/TR/MathML2/chapter1.html#intro.goals) This provides a rationale for adopting MathML in favor of ISO 12083:1994. As for MathML vs. TeX, Knuth's TeXbook says: "This is a handbook about TeX, a new typesetting system intended for the creation of beautiful books---and especially for books that contain a lot of mathematics." (http://www.ctan.org/tex-archive/systems/knuth/tex/). That's not ODF's goal. OpenOffice.org uses MathML's <math:annotation> element to store a TeX-like representation of the formula; example: <math:annotation math:encoding="StarMath 5.0">a over b + 2</math:annotation> Future ODF specs could recommend putting in a TeX-encoded annotation, given that there are MathML to TeX converters (http://www.mathmlconference.org/2002/presentations/smirnova/index.html)
