A better way to define an xelatex command appears to be with
'TeX-run-TeX':

INS DEL Name: XeLateX
            Command: xelatex "%(mode)\input{%t}"
            How: Value Menu TeX-run-TeX
            Create a process for NAME using COMMAND to format FILE with TeX.
            Prompt: Toggle  off (nil)
            Modes: Value Menu All
            Menu elements:
            INS

Interaction works, toggling (C-c C-t C-i) works, modeline process
reporting works, and most importantly, error parsing works (which it
doesn't with ...run-command and ...run-interactive).

An even better way, as I suggested early in this thread, is to define
xelatex as a latex command style.

INS DEL Regexp: \`fontspec\'
            Style: xelatex
INS DEL Regexp: 
            Style: %(PDF)%(latex) %S%(PDFout)
INS
   State: SAVED and set.

Everything seems to work, including file parsing. Note that if you do
it this way, auctex will tell you that it is running latex.

I'm using emacs 23.0.0 (unicode2).

My impression is that interactive mode (C-c C-t C-i) is about buffer
management rather than actually switching the interactivity of an
output buffer.

send-invisible is a comint mode function, for any process buffer,
rather than an ordinary (auctex) user function.
