This function manupulates implements operations on aggregates of EDMprotectedData instances. Dependent of the actual aggregateOperation, this functions takes 7 or 8 arguments. The optional "aggrOperationCondition" defined in the related xpxDefineProtectedData() must must evaluate to TRUE before this function can be successfully performed. The optional "aggregateOperationCondition" must evaluate to TRUE before this function can be successfully performed.

For all write operations: The actual EDMprotectedData must be defined with xpxWRITE_ACCESS and the optional defined "writeCondition" must evaluate to TRUE. No EDMtransaction must be open when this function is invoked. An EDMwriteTransaction will be stated by this method and committed when successfully performed, and aborted when this methods fails.
For all read operations: The actual EDMprotectedData must be defined with xpxREAD_ACCESS and the optional defined "readCondition" must evaluate to TRUE.
