Did he present it as if it was real ? AFAIK.

Was that a fake official document ? No.
AFAIK it wasn't written passport, using its colors. Only layout and text
was similar, but with safeguards.

(also see last paragraph)

I agree this is a problem, but in that case, you can now only rely on
trust chain and spotters to guarantee it was the same (which doesn't
makes any difference as you won't sign it now).

Learning from his address that he belongs to CaCert, you should head for
their stand at next fosdem and do the ID verification tests. They'll
probably show up.

(caution, pls do not incriminate cacert for the key-signing stuff)

Seems ok to me. He didn't try to acquire any benefits fraudulently and
even explained when spotted.

I would also quote FOSDEM's keysigning instructions:
" Please bring the printed list, a pen and appropriate form of
identification with you to FOSDEM 2016"

I can try to find any violation, i can't.
He had a list, a pen and a form of identification.

"After the participants have verified each other's identity, (...)"

Again, nothing here says that the form of ID must be official, issued by
a state.
