Clarify the use of (under) saksmappe
ab13596a is commit I am accepting without being in agreement with the commit. To be bluntly honest my interpretation of the Noark 5 API is that it is not a high quality document where the National Archives have given the standard the necessary work that one would expect. There are so many things there that still need clarification. One of the things I believe we need clarification on is if a saksmappe can contain an (under)saksmappe. This commit introduces this concept as a rel/href pair.
I am not sure if there are any implications of allowing (under) saksmappe. Perhaps it is unproblematic, perhaps there are unforseen problems and I believe that this is an issue that should be adressed by the National Archive. But if nikita is to be able to serve as a reference implemetation, we have to follow the Noark 5 API.
I am creating this issue to make a note that there is code in the nikita codebase I am unsure about.
