Hello everybody,

Sorry to be late with my comment.

I think another aspect that came up in discussions was the issue of 
"clean SVG" (see e.g. https://www.svgminify.com/ or search for the 
term). Tools such as Illustrator and Inkscape have the strong tendency 
to include a lot of additional information and cruft.

When you draw a single rectangle, you'd expect that would result in a 
single <rect> element (and that would indeed be enough to render the 
result correctly), but what you end up with is something much more 
voluminous that may not even contain a single <rect> element.

I attach a document created by Inkscape and one created (from the 
former, in this case) by hand. Inkscape actually uses <rect> when you 
draw a rectangle; I think it is (or was) Illustrator that didn't. 
Anyway, the difference should be quite obvious.

I'm not sure how "clean SVG" could be formalized, but getting close to 
it for SVG is probably as desirable as having clean semantic XML.

Regards,   Martin.
