Such code trying to guess the graphic extension from within
the stylesheet is a good idea. Anyway, it will always face
the same problem : for publishing in HTML, for example, how
to decide whether to add JPEG, PNG or GIF ? It's not easy.

I'm currently using the following approach:

	<graphic fileref="foo.&gif-eps;">

stands for:
	"use foo.gif when making HTML files, foo.eps when printing
to TeX."

You can do create on the same model other entities like
&jpg-eps;. It's not perfect, but it's simple and works.
