Method 1: Modifying XML Load Files Directly
Before you begin the following procedure, ensure that you have XMLSpy or another XML editor that can validate the XML against a DTD.
1. Make your changes to the \Windchill\loadFiles\csvmapfile.txt file.
2. Add the required DTD elements to the csvmap.dtd and generate the runtime validation DTD through the wt.load.util.UpdateEditDTDUtility.
The runtime DTD is generated in the following location: <Windchill>\codebase\registry\ixb\dtds\standardX20.dtd. Your changes are propagated to the <Windchill>\loadXMLFiles\standardX20.dtd file.
For more information, see About UpdateEditDTDUtility.
* 
The csvmapfile.dtd file is a partial DTD and therefore cannot be used for validation. To obtain DTD file for validation, run Windchillwt.load.util.UpdateEditDTDUtility.
3. Using an XML editor, make changes to the XML data files and validate them against the DTD that you obtained in step 2.
