I agree with you that I can use this workaround.
But is it really fine to define a "writing" interface as a sub-interface
of IReadContainer which, as said before, just need reading
permissions ??
Using "attributes" here in ZCML is only OK because we have a single
method in IOrderedContainer interface...

Thanks anyway,
