Right.

No, it isn't formatter-specific at all. I'm not sure what you are trying
to say here.

I hope not; SVG is explicitly intended to be stylable. For example, you
can link to a symbol library and then restyle those componenents.

They are hardly ever used in other vector graphics l;anguages because
no-one saw the need, until now; and I think that the reason many
wordprocessors do not have their stylesheets used much is because the UI
is clunky and thus patchwork overides are easier for users than
structured styling.

Yes, there are only so many numbers you want to type in by hand

You don't know that, unless you are aware of more product plans than I
am

They may not, but the generated SVG can still be styled even if the
original generating application did not produce any styling.

OIK, I see where you are going. Yes, inline style in SVG is perfectly
fine (although not the only option) and, for inline style, CSS is
suitable wheras XSL is not.

I don't see that it is difficult to use and process.

External stylesheets and inline stylesheets are both stylesheets. One
just has implicit selectors, is all.
