It is indeed "a patched version of TeX", but the "patches"
are very powerful and provide much-needed functionality :

This last part is very exciting.  UTF-8, native fonts (quite the
reverse of "alien", really !) -- these are the things that make
XeTeX so useful, but XeTeX's future is uncertain, and whilst
some may argue that LuaTeX is that way of the future, others
are less sure.  A KerTeX version of XeTeX, with the possibility
of some further rationalisation and the possibility of further
development, would be a very exciting prospect indeed.
