Not knowing any better, I noticed that the DTD lists "tex" as a valid graphics
extension for <graphics> and <imageobject>. I just added a bit to
the print part of my customized copy of cygnus-both.dsl:
(define %graphic-extensions%
 '("jpg" "png" "tex" "gif"))
;;What is the default extension for graphics?
(define %graphic-default-extension%&nbsp;
 "tex")
(define preferred-mediaobject-notations
 (list "TEX" "JPG" "JPEG" "PNG" "linespecific"))
(define preferred-mediaobject-extensions
 (list "tex" "jpg" "jpeg" "png"))
(define acceptable-mediaobject-extensions
 (list "gif" "bmp"))
(define acceptable-mediaobject-notations
 (list "GIF" "GIF87a" "GIF89a" "BMP"))
Now I can simply put tex equations into a file, e.g.
\begin{displaymath}
\int H(x,x')\psi(x')dx' = -\frac{\hbar^2}{2m}\frac{d^2}{dx^2}
\psi(x)+V(x)\psi(x)
\end{displaymath}
and refer to the tex file as with any other graphics file:
<equation>
<title>this is an equation</title>
<mediaobject>
<imageobject><imagedata format="tex" fileref="figures/eqn.tex"></imageobject>
<imageobject><imagedata format="gif" fileref="figures/eqn.gif"></imageobject>
</mediaobject>
</equation>
Pointing jade to the modified dsl, the tex backend renders the equations
beautifully. I provide a gif for the sgml backend. No changes to the DTD
and just a little added to the front of the dsl. For an example, see cator.hsc.edu/~kmd/docbook/equations/
