Yes, that is correct. 18,0 refers to the selected variant and 21,0 
refers to lowercase numbers.

The geometry package has an option to set the page height to an integer 
number of line heights, which might help in this regard.

I haven't had a change to do any typesetting with (almost anything at 
all, let alone) Zapfino, but I've been wondering for a while how you'd 
be manage with the colliding ascenders/descenders in any manner 
whatsoever. Sounds fun, but I fear it might be the case that a GUI 
program might be easier to deal with.

What would be nice is a GUI program for setting small amounts of text 
with various per-letter settings like variants and kerning which could 
then output the corresponding XeTeX commands. I'll add *that* to my 
list of things to do if I ever get around to learning Cocoa :)

Just some insomniac (rare for me, I assure you!) ramblings.
