I think there is a misunderstanding. All the functions in 'svg
basically do what you sketch in your mail (i.e. manipulate a dom
as an abstract data structure with an XML representation: so
basically generate and serialize XML) and don't rely on librsvg
et al. (I guess that is what you chastise as "unsafe foreign
library").

Librsvg is used to display the svg in-buffer, as libpng is used
to display PNGs in-buffer. Feel free to re-implement that in
Emacs Lisp ;-)

That's interesting -- and this is the part librsvg is an alternative
for.

How does the emacs framebuffer work? Can it display images as
parts of a regular Emacs buffer?
