Error: An error occurred while parsing the XML document. Error number : 516
Schema Wizard returns an error when importing a XMI file:
"An error occurred while parsing the XML document. Error number : 516"
The uml.dtd file does not exist in the same directory as the XMI file.
Solution or Workaround
The file uml.dtd must be present in the directory that contains the XMI files.
- Copy the uml.dtd file from the appropriate location. For ArcGIS 8.x, the default location would be C:\ArcGIS\arcexe83\CaseTools\Utilities. For ArcGIS 9.0, the default location would be C:\Program Files\ArcGIS\CaseTools\Utilities.
- Paste the uml.dtd file in the same folder as the XMI file being used.
