A zettel representation that tries to recreate a [Markdown](00001008010500) representation of the zettel.
Useful if you want to convert [other markup languages](00001008000000) to Markdown (e.g. [Zettelmarkup](00001007000000)).

If transferred via HTTP, the content type will be `text/markdown`.

Please note that many elements of Zettelmarkup cannot be encoded in Markdown / CommonMark.
Examples are:

* [Description lists](00001007030100)
* [Verse blocks](00001007030700)
* [Region blocks](00001007030800)

* Most [text formatting](00001007040100) elements (except emphasis and quotation)
* Most [literal-like formatting](00001007040200) (except literal text / code spans)

Some elements are restricted, e.g. [quotation lists](00001007030200) are only supported as a top-level element.

Restricted and unsupported elements are not encoded.
They will not appear on the encoded output.

Maybe in the future, ignored elements may be shown as an HTML-like comment.
