No. The semantics are that you've verified the person matches the key.
Photo ID's are *one way* of doing it.

http://www.gnupg.org/gph/en/manual.html

The GNU Privacy Handbook says (under 'Importing a Public Key'):

"A key's fingerprint is verified with the key's owner. This may be done in
person or over the phone or through any other means as long as you can
guarantee that you are communicating with the key's true owner. If the
fingerprint you get is the same as the fingerprint the key's owner gets, then
you can be sure that you have a correct copy of the key."

Now, if you're doing a PGP keysigning, then yes, checking government-issued ID
is probably the only sane way to verify 50 or 100 people's identities in an
hour. But if you have other trustable channels of doing so, that's considerd OK
too.
