[AUCTeX] Can xetex be used in auctex?

[Ed C.]

I learn from the web that miktex 2.7 includes support for xetex but I 
get nothing but many pages of errors when I try to compile the sample 
code at:

http://en.wikipedia.org/wiki/Xetex

Also, if xelatex is a command line program why does xelatex --help 
reveal that it doesn't need any arguments??? Is it possible to run this 
tex variant from auctex?

Thanks,

Ed
