    Well, my viewpoint is that it is sufficient to
    1/ not require committing to information from other ontologies unless an
       explicit directive so stating is present
    2/ behave reasonably when referenced documents (or other resources, such as
       computing resources) cannot be found, or accessed, or are unresponsive,
       probably by continuing reasoning but not labelling results as complete.
    The first is a matter of the logic, the second has more to do with
    interface design.
