If a file fails these checks, MUST it refuse to load the file, or can
a conforming implementation attempt to parse it as a different file?

That is, do these checks occur past the point of no return, or can
they be part of the "check what kind of font this file is" algorithm,
allowing a conforming implementation to then attempt to load it as a
different kind of font (such as EOT-Classic)?
