Perhaps Knuth thought it trivial to create a new font metric file to
incorporate spaced caps. I agree a tracking method in XeTeX would be
In both cases, the natural kerning would be respected and adjusted by
the specified amount. Contrast this to the present behaviour
which kerns the letters exactly by the specified amount.
This makes fine-tuning slightly more difficult.
\addkern could be implemented, slightly more roundabout, using macros
by measuring boxes.
I can see the disadvantage to allowing tracking (he who would steal
sheep and all), but on the whole it does seem strange that the
capability is lacking.
