Comment 12 for bug 366744

Here is one way to write SVG using kerning that Inkscape will edit correctly. The trick is to wrap all of the <tspan></tspan>
pairs on a single line with an outer <tspan sodipodi:rule="line">(all the other pairs)</tspan>. The attached example is like that and it seems to have few if any editing problems. One could argue that what it does for a "return" when the cursor is inside a vertically kerned section isn't right. Rather than moving the baseline of the remaining line down to the next baseline, it moves
the baseline of the vertically kerned section down to the next baseline. This drops a superscript to the baseline, and drops the baseline text below the baseline.
