Document link types

One difficult issue to tackle is the proper "direction" for document proposition links.

I suppose if the proposition is commenting on the document, the proposition should point to the document. After all, in this case the proposition makes no sense without the document, it doesn't "stand alone".

On the other hand, if the propositions are being derived from the content of the document, the document should point to the proposition. Or if the document provides supporting arguments or evidence for the proposition, the document should point to the proposition.

If we go with that, we get links like:
