Sincere apologies, Ulrike.

Well, yes, of course I could.  But I assumed (perhaps naively)
that just as e-TeX had provided the e-TeX logo in a file that
was compatible with Plain e-TeX, XeTeX would have done the same.

I do appreciate that I am now one of an endangered minority of
Plain users, but XeTeX is an /engine/, not a format, and it
seems crazy to me to provide a definition of its logo in style
files that are compatible only with LaTeX.  Your demonstration
that Hologo.sty /can/ be used with Plain XeTeX is helpful, but
of course I am put off by the fact that it warns me that it cannot
find a free read register.  I have no idea why it might want one,
but if it can't find one, then presumably it won't necessarily
work as expected.
