Allow markdown formating in "Description"

Allow at least emphasis and code via ** and ``

See for instance this record that tries to use such formating: http://hdl.handle.net/11234/1-5672

What I'm thinking: We should be careful with that, when we officially support this shouldn't we somewhere express the different semantic, eg. by specifying text/markdown (https://www.rfc-editor.org/rfc/rfc7763). Should we drop the formatting in (oai-pmh) exports?

Hmm, those are good points. Especially the exports are something to worry about. If we supported e.g. tables in markdown, it could break into a complete garbage when formating is removed. We certainly do not want that.

Are there some precedents, or is metadata always and everywhere (by definition) plain text?
