'' This data template sample loads a DOCX that was created in MS Word,
'' And contains a table with data template tags. It then creates a DataSet,
'' loads the GcNwind.xml data base into it, And builds a product list
'' from tables in that data set. The product list Is set as the template
'' data source on the document, And the template Is processed to build
'' the final document with actual data.
