Emmanuel Lecharny commented on DIRSTUDIO-913:
---------------------------------------------
Stefan, your analysis is correct.
We have added a flag in the Schema Manager that allows someone to modify the
schema (add or delete elements) without doing any check (ie, you may be in an
inconsistent state at some point), and a method that does a check at the end.
This is what we call the 'relaxed' schema.
We could leverage this feature, but that would require to send a control to
tell the server to switch to a releaxed mode, and another control to tell the
server to switch back to a checked schema (and validate or invalidate the
modifications).
This is quite a bit of work, but it's feasible. I don't think we need t for the
current version of the server...
