+The string macro [`@MIME_str`](@ref) allows `MIME{Symbol("...")}` types to be specified more succinctly
 as `MIME"..."`, for example `MIME"text/plain"`.
 Singleton MIME types can be used to add new methods to the [`show`](@ref) function.
 
 A `MIME` **instance** is created by calling the MIME constructor, either directly,
 e.g. `MIME("text/plain")`, or after the string macro, e.g. `MIME"text/plain"()`.
 A `mime::MIME` instance can be passed as the second argument to [`show(io, mime, x)`](@ref)
