Salve,
I've recently developed a module with full support for AMSLaTeX, Lilypond and Chess;
and I wanted you to take a look before I incorporate it into Wiki.
WikiTeX introduces a new element, the "rend" element, which comes in
block and inline form:
<rend class="music" style="tempo: 50" value="[content]"
/>
or:
<rend class="math">
[content]
</rend>
The rend element is indefinitely expansible by class modules, of which
"math", "music" and "chess" are now supported.
