Re: specialized scripts as alternate text

After your answers, I agree with both of you.
Naturally, if I would keep a personal knowledge base written entirely in xml
and have to interface with multiple operating systems, I could also use a
portable version of Firefox, for windows / unix, solving also the
compatibility issues.
But how would be possible to implement the second idea, that is:

- put in the html both Math-ML and jpeg figure
- if the browser can read the Math-ML, then ignore the image
- if the browser can't understand Math-ML, then load the image

Is there a solution which can be afforded with XML techniques, not relying
on third party applications?
Obviously, I'ld like ALL PCs could interpret ALL standardized XML scripts,
but....

Thanks to both !
