TransactionChangeDescription
A composition of zero or more change descriptions representing the
changes performed by transactions in a possibly nested structure. In the
execution of a transaction, the changes that it makes in between nested
transactions and the changes made by those nested transactions are stored as
discrete
ChangeDescription s in a composite. The composite structure
is recursive.
