A process that wishes to export a transaction uses this interface to marshal a transaction object. The process calls this interface and passes a transaction object. The process is returned an opaque marshaled form of the transaction object called a transaction cookie. The process then sends the transaction cookie to the destination process. This is referred to as exporting the transaction.
Communication failures may invalidate the export object. If ITransactionExport::Export returns the error XACT_E_CONNECTION_DOWN then the current export object is invalid and a new export object must be created.
