    Both points valid.

      * A node can belong to multiple categories
      * The categories are assigned by users
      * A node can change categories, have categories
        added and have them removed.
      * Categories can change
      * Any layer that uses categories for automated reasoning
        that assigns "meaning" to the categories will be a
        layer that operates above the basic system.
      * In the system itself, you will be able to search
        based on categories, or text, or links -- or combinations.

    Additional Notes:
      * I agree with Eugene (in principle) that links should
        be categorizable. I have been calling that feature
        "typed links", but it undoubtedly makes sense to reuse
        the category-capability to accomplish that typing.
      * Just to be sure, though, I think it behooves us to come
        with a use case that requires them. The first idea I
        came up with was "all design notes corresponding to this
        version of the system requirements" -- but that search
        can be satisfied using the type of the link target.
        Any other cases come to anyone's mind?
