If the section spec has changed, it means that parameters of the Directive have changed and/or the Technique version has changed, so the unmergability will be found)

The Technique can't changed, (or only if LDAP/archive data has been checked so they don't need to be checked)

We only keep the root section and the technique to be able to display the value in the webapp, and are used to verify that parameters are well formed

for the merge, we were onoly compaiting directive, i wanted to restrict to the same level.
