Makes sense.
We could also link to individuals having published there simply.
(the activemath group had a similar economy of publications but it has been private)

The paper at the workshop is linked from here:

and which Florian Rabe presented at that same workshop.

Arguments against were in several other directions, the biggest being that it was yet another feature of MathML and one that was not completely mature. I still claim against XSLT that such an approach was more declarative and thus more safely exchangeable, the paper http://www.hoplahup.net/paul_pubs/openmath-utility.html gives some arguments about it.

Note also that there has been quite many other notations' based rendering libraries rendering OpenMath to some of HTML, TeX, or MathML presentation (e.g. that of Watt-Naylor, that of Smirnova-Watt, that of OMDoc 1.2, that of the OpenMath website, ...).
Each attempts to answer its particular set of challenges with its particular type of technology.
That of the Kwarc team aimed at a bigger simplicity with more flexibility in the interactiveness of the rendering, that of the ActiveMath group stemmed from the need to adjust the notations based on language and other factors, Smirnova-Watt aimed at a user-interface for authors to choose from.

Thanks for spotting. Done.

Nonetheless, rewrite redirect rules at jem-thematic.net would make a lot of sense.
