Analytics in the data extraction is not relevant to DQC. I've only ever deployed the 4.0 (OrgAudit) version and in that version the AdminConsole section is not visible.
Also, regarding your & vs & observation ... this makes no difference to the configuration as both are valid in the XML config files. Just so happens Nakisa deliver it in one format but as soon as you save your build it updates in the other format.
Are you just deploying? (if so, why version 3.0?)
