composing HTML documents with text + Maxima stuff



I'm interested in composing HTML documents, to be displayed on the
Interwebs, comprising text and Maxima input and output. I know that
wxMaxima exports sessions to HTML, but from what I can tell, output
is always exported as images and plots are always exported as png --
I'd like to try MathML for Maxima output and svg for plots; I think
those would be better for web pages. I suppose it would be
straightforward to put together some kind of klugeriffic document
processor -- texi2html seems like a suitable starting point -- but
maybe I needn't reinvent that particular wheel. Thanks for any info.
