If your XML Pipeline uses built-in DataDirect XML Converters - to convert CSV or EDI to XML, for example - you need to purchase licenses for the DataDirect XML Converters you wish to use if you wish to deploy your code in any environment on a machine (such as a test or application server) that does not have a license for the DataDirect XML Converters. Licenses for DataDirect XML Converters are purchased separately from Stylus Studio 2009 XML Enterprise Suite.
