forbid edit rights below

Hi,

in a folder-branch X of a zms site there is group A of people who have
edit rights. I have a subfolder Y in this branch where group A should
not have edit rights, but group B. But with 'native' permissions group A
can write in the whole branch because of acquisition.

There is the possibility to break permission-acquisition by using the
manage_access screen of Zope for the folder Y and deactivating
acquisition for the ZMS_Author permission. But this is not the ZMS-way
of doing permission things.

Is there a better way for doing this?

It's struck me that the desire of people to market the RUP as the single
process led to a result where people can do just about anything and call
it RUP - resulting in RUP being a meaningless phrase.
