It seems strange and confusing to me to mix the informal prose with the
formal ABNF syntax; I rather think of them as

  placeholder = <this rule is not expressed in ABNF here>

so I expect the right-hand side to either be only a prose value or to be
free of prose values. I am not aware of encountering counter-examples in
the wild (except being confused by RFC 3986's `path-empty = 0<pchar>`).
