for backwards compatibility with jackrabbit we should also implement
the ability to import protected items.
while import version content is most probably unique and system defined,
there are quite some areas like user management and access control that
need to be pluggable and thus the particular import behavior should be
defined by the corresponding implementation.
i envision this to work in a similar way than the implementation
steps to get there include:
- properly setup the xml-import such that it recognizes protected items
and calls the configured protected-item-importers.
- allow to plugin implementation specific extensions
- define an interface for that protected item import.
regarding the latest part: in contrast to jackrabbit core, where we had
just the JCR API at hand i would suggest to setup those special importers
such that they can operate both on the JCR API (session and extensions)
and on the OAK API giving the implementation more flexibility on how
to actually treat the import.
