This is based on my action item to review ISO 24751 for potential requirements of interest in the User Contexts work. ISO 24751 enables the priority of each need/preference to be asserted. More specifically, it distinguishes needs (which must be satisfied for a resource to be accessible to the user in a given situation) from preferences. Optional and prohibited adaptations are also distinguished, but I think the most useful distinction is that between "required" and "preferred" items. Our User Contexts API, as currently drafted, treats all needs and preferences equally, whereas application authors might want "hard" requirements (i.e., needs) to be distinguished from preferences. I don't think this issue can be easily resolved in isolation from use cases and the wider questions currently before the group regarding what should be included in the User Contexts specification. It is, however, a design decision that should be made deliberately and with an understanding of its implications.
