It's actually called Linuxdoc-SGML 

... AND one can create plain text output (ASCII and ISO-8859-1), DVI,
PostScript, HTML, GNU info, LyX, and RTF output from a single SGML
source file (I don't know whether something for conversion to nroff
already exists).

... AND it supports math

I don't know about using it on non-Linux systems, but there should be no

It (or a similar SGML DTD) may really be the optimal solution for
WRITING documentation.  However, just installing the SGML sources for
PROVIDING it most likely does not make too much sense, because it would
require conversion tools which are not standard.

Of course, when providing pre-formatted versions rather than sources,
index and keyword databases should come along with that.
