When you create a new stylesheet in iManager or Designer, it is pre-populated with a stylesheet that implements the identity transformation. In the absence of additional templates, the identity transformation allows the input XML document to pass through the stylesheet unchanged. You usually implement policy by adding additional templates to act on just the XML that you want to be changed. If your stylesheet is being used to translate a document to or from an XML vocabulary that is different then XDS (such as the Input and Output Transformations for the SOAP and Delimited Text drivers) you may need to remove the identity template.
