Re: [css-writing-modes][svg] Embedded SVG and inheritance

The first thing that struck me here is this isn’t far off from what folks want to be able to do with SVG-in-OT…in that you can have glyphs that inherit their state from their “parent” context.  Having direct SVG inside of HTML, that could potentially inherit the styles - would imply that what is good for one would be good for the other.

Can you explain why this is “unlikely to be web compatible”?  And then if so, why the SVG-in-OT work is acceptable?

Whatever we do for you, we should do for the other - IMO.
