<xs:documentation>WellCMLedger Schema. The "event ledger" concept is this: each time an activity associated with a well happens, that event is recorded in the ledger. This collection of event history is what makes it possible to support the completion use cases (snapshot in time or the cumulative history of a completion).</xs:documentation>
