    It seems to be hard to find a complete list of the possible contexts; as far as I could determine, besides the ‘display’ context, there is also the ‘db’ context (which has its own set of encapsulating functions), but I couldn’t find a reference to the full list of contexts.

    (The same comment applies to esc_url() too, of course; only ‘display’ is mentioned there as well.)
