Although this functionality is primarily to allow Arbortext products to access Windchill-managed XML applications, other files types, such as word documents or text files can also be accessed. In order for the anonymous access URL to work, the target object must be a WTDocument object (or subtype thereof). You cannot access other Windchill object types, such as EPMDocument objects (CAD files or Arbortext Editor-created XML files) or WTPart structures.
