3.2.5.11 NumExportUpdate
The NumExportUpdate method returns the number of objects that will be updated in the data source on the next export.
If the server is unable to communicate to any implementation specific components, the server SHOULD return connection-failure<13>.
If a failure occurs for which there is no other more-specific SOAP fault specified in this document, the server MUST return call-failure.
Otherwise, the server MUST return the number of connector space objects that will be updated in the data source on the next export.
