Load Snapshots Anonymously
You can also load snapshots as a dataset into a local, anonymous variable with the snapshotquery attribute in <raql>. This example is identical to the named example shown previously except that the query to load snapshots in a dataset stream is specified on <raql>.
The full EMML for this sample is:

</operation>
