This seems a little erratic; for example, Hoefler Text gives a
fontdimen1 of 0.0pt. Should this always give some sort of positive
value for italic fonts, or will it occasionally break?
If the former, I'll leave \emph alone; if fontdimen1 isn't reliable,
I'm happy to patch the LaTeX command to work correctly always
(although I'm somewhat hesitant to do so...).

I'm in two minds about this. On the one hand, it would make it easier
for the macro writer to write a high-level syntax like I've done in
On the other hand, I have already written it in fontspec, and it
isn't that complex. I'm more of the opinion that primitives should
generally only be introduced when they simply can't be done (or can't
be efficiently) with macros.

Yep. I think TeX-based syntaxes needs as much error correction as
possible, which is tricky without conditionals to check if the input
How about \XeTeXfonttype = 0, 1, 2 = doesn't exist, legacy TFM, or
(AAT vs. OpenType is meaningless because one font can contain both
