Such a Description can be accessed by right clicking the svg image and choosing the option Description.

I want to replace all the svg images using a suitable macro, by the embedded descriptions.

e.g. from

The Einstein's famous equation, E = mc^2, tells us that mass can be converted to energy and vice-versa.

This will allow me to convert by hand the odt file containing numerous TexMaths equations to LaTeX.
