A chargeset defines how the turnover associated with the property will be charged to one or more accounts. A property may have any number of charge sets, but each chargeset must deal with a different top-level account. A charge set consists of one or more accounts. Each account must be a leaf account. The account ID may be followed by a percentage value that determines the share for this account. The total percentage of all accounts must be exactly 100%. If some accounts don't have a percentage specification, the remainder to 100% is distributed evenly between them.
