specialized scripts as alternate text

About the use of specialized XML standards, such as MathML, SVG, etc., this
is a marvelous feature of Amaya, apart from its double function of composer
/ browser.
But let's suppose to include these specialized scripts in our pages and the
remote viewer has not this standards implemented in the browser / reader
(explorer, Firefox, etc.).
So it could be possible to render SVG, MathML formulas as images (e.g. jpeg)
and include them into XML pages.
Anyway this solution would lose information and the composer would need to
keep an extra (original) XML version with MathML scripts inside instead of
the images.

So my suggestion is:
*why not to include the specialized scripts as alternate text of the image
rendered from the scripts* (this would be done, for example, during
generation of X-html from XML files) and instruct in some way Amaya to
interpret the content from the alternate text? *Or, as opposite concept, to
use an 'alternate image' as secondary way to load the content* for browsers
which have not the capability to interpret the primary XML sub-script.

This would allow also to 'update' image content on the fly using the
original files without information loss.
