The messages are clear to me.

But I have some questions:

1- The clamVersion attribute did always existed on the clam network 
files?  (I cannot found it in the CHANGES log) If not, there are 
probably no clam networks so much outdated being used... but what would 
happens if it doesn't exist? From 
http://doc.trolltech.com/4.5/qxmlquery.html#evaluateTo-4 : "If output is 
null behavior is undefined."

2- What would be the behavior in case of different versions? I think 
that checking the version number is OK as a first test of possible 
conflict between releases, but the needed changes and the definitely 
tests should be done looking in a migrationScript file or something like 
that. How we would deal with the different migrationScripts that we have 
in the core and different plugins? We would include all of them in the 
NetworkEditor to make such a test?

3- David: do you think that it would be difficult to put the interface 
to check the network version on the CLAM::XMLStorage class? I know that 
this improvement  and interface to  solve the version conflict is 
inherent to the NetworkEditor, but CLAM::XMLStorage would not be the 
ideal place to just check the version? Maybe returning diferent error 
codes on the Restore...



If we maintain updated the migrationScript(s) file(s), this would be a 
very nice tool. :)


Best regards,
Natanael.
