Hum,

1) ISO 12083 is a big subject. Mathematical part of ISO 12083 are a few
pages.

2) I never saw criticism to the mathematical stuff as <fraction>, <den>,
<radical>. For instance <sup>, <inf> and the model for prescripts continue
being used by Elsevier in his new XML workflow (look example of markup I
provided here).

3) Yes, ISO 12083 contains problems but can be admended (apparently a new
standard will be prepared by the ISO commitee) and used in its strengh
points (some would exists :-) instead reinventing the wheel (MathML WG
did).

4) Main lack of interest by publishers on ISO 12083 was because the
standard born just when SGML began to lack popularity in favor of the new
XML paradigm.

5) Even today, the old ISO 12083 is able to encode mathematics that MathML
cannot, e.g. certain script structures using less tags and more simple
data model than p-MathML.

My citing of Elsevier was because next MathML 3 could introduce the
in-house modifications (or part of). Standards may work and in-house
modifications indicate weakness.

Please be more explicit and clear with you query
