offers some explanation, but does Panther support type identifiers.
I don't think so as I don't set a "type identifier" listed in the
"info for" properties.
There's more than one strategy for type identification. The
"official" one supported in OS X is still file name extensions. But
it does support the old Mac OS type and creator codes too, though it
doesn't require them. The metadata also supports MIME types as
identifiers too. The new UTI that Bill Cheeseman was talking about in
the archived message you linked to above is a system of typing that
solves a host of typing issues, and can still make use of the other
typing mechanisms through cross-referencing of types to a UTI type.
