Hi, Last week I upgraded (I think from Oxygen 7.1) to Oxygen 7.2 which is using Xerces 2.8.0 for schema validation. Suddenly XML instance documents that are definitely not valid are being called valid by Oxygen. I am using the red "checkmark" button for which the tool tip is "Validate Document". I am creating the files by opening a new document in Oxygen and attaching a schema that way. Documents with no content in the elements as well as documents that are just completely wrong are coming up as valid. When I validate using Xerces at the command line (java sax.Counter) I am getting the proper errors for these same documents. Additionally, I am getting the proper errors in Oxygen when I try to validate the schema itself. What could be going wrong?
