MathML, using Paul Wang's package



I've downloaded the MathML package maximaMathML from the share/contrib/
section and installed this. Does anyone have experience of using the
mathML generated in web pages?

I noticed some comments on the mailing list archive on 11 June, but this
doesn't answer the specific questions below. I would very much appreciate
the experiences others might have in this area.

(1)  The tex() function has an option

s:tex( 1/(1-x^2), false);

to return the tex'd value as a maxima string.  Is there a way to assign
the output of Paul Wang's ctmathml function to a stgin in a similar way?
This is because I'd like to concat the mathml'd expression with some other
stuff to generate a web page, which I can save.

(2) Does anyone have experience of actually using the MathML package with
web browsers?  I'd really like to do this, having maxima generate
expressions on the fly.  I don't mind using a plug-in on the client side
if necessary.

Many thanks indeed.
