We still need to decide who can add a new extension, and who affects such an
extension. My first idea is to allow anybody to add EPs and IEs, but unless
such a document is certified somehow, it will only affect the current user.
We need to make the distinction between global and user-specific extensions.
This complicates a bit the algorithm for fast IE output, but I think we can
manage to keep it fast enough.
