Hi All, I have been trying to use an XSD catalog file for months without any luck. As a matter of fact I have *never* been able to get XSD catalog files working on Oxygen. Currently I am using Oxygen 7.0 on a Windows 2000 platform. The best I can do is the following error: http://asdd.ga.gov.au/asdd/work/catalogerror.txt The catalog preferences look like this: http://asdd.ga.gov.au/asdd/work/catalogpreferences.gif The catalog file looks like this: http://asdd.ga.gov.au/asdd/work/catalog.xml I am using the following catalog.xsd: http://asdd.ga.gov.au/asdd/work/catalog.xsd I don't understand the error. The path to the catalog.xml file is correct and it is readable. Why is this error occurring? I can only find catalog files for DTDs not XSDs. Thanks. John
