In most cases after a template is run, XpressDox will save the Data Set (i.e. the XML file containing the data).
Sometimes you might want to suppress the saving of the the data set. For example this might be when all the data for the data set are sourced from a database or perhaps where the template is only ever used to assemble a document from data sets already captured or prepared in some way.
will instruct XpressDox not to save the dataset after the template has run.
