    - Specific Datatypes
    - Generic Solution (transforming nodes)
        Remarks: we don't transform any nodes, we query for title/authors/date
                 my implementation for finding blocks and inlines is like a SYB query, but it doesn't use SYB (possible doing the same with SYB reduces overhead but I don't think so)
    - Implementation (of such a type)
         It should be made clear that OTag represents an opening tag and that CTag represents an closing tag. Also it should be made clear that the Meta from the datatype is some other Meta information then that of the Pandoc type (Meta in HTML contains e.g. document encoding and search engine info)
- Generics
    - Obtaining Meta Information (using SYB)
    - Obtaining Blocks and Inlines (our 2 approaches)
