I have an issue with my XSD Schema. I keep getting the error mentioned in the title. I don't understand why it says that a certain element is not allowed in another. It doesn't complain about the 'accessrights' but it does about the 'settingvalue' when both of them are essentially the same (just a few basic elements; strings and booleans).

Does anyone have an idea about why it's complaining? I am using Apache XMLBeans 3.0.1 (from the Windows 10 CMD) to try and validate the schema.

The XSD Schema file, in its entirety.

An example of how an XML that conforms to the schema might look like

 <dependency>IDStringOfOtherLicense</dependency>
