(I'm not totally sure what you mean by "multiple paths" here, but I'll 
assume we're still talking about the quoted-string/token choice).

I would argue it's implicit in how the ABNF defined.

When the ABNF indicates that an extension parameter or directive uses

   quoted-string / token

then, yes, this means recipients MUST support both.
