What is the best way to configure/implement default pre-publishing validation?

Hi,

I am using Foswiki in a pretty large corporate environment, in France, with strong policy rules. Management acceptance on the project would benefit from a pre-publication feature.

This would not be very strongly enforced, here is how i see it :

- A user modify a topic

- Topic variable VALID is set to 'NEED_VALIDATION' in this new version (ex: r2)

- Until validation the default version displayed is the version in which the variable VALID is set to 'VALIDATED' (ex: r1)

- When a validator press the validate button, the variable VALID on the last version becomes 'VALIDATED', thus becoming the official (defaul) version (ex: r2)

Note that The user can access the last version manually, even if it is not validated yet. This is not a problem for me. However, the central point here is to make the default version displayed not the last version, but the last validated versionn, wiki wide

How could i implement this feature?

I installed and tried the Approval/Workflow plugin, but it is very complicated, and not adequate for wiki-wide simple validation. Or maybe i just dont know how to configure it
