Cannot rename attribute in XSD

I am trying to generate Java classes from our XSD and we have a duplicate attribute name in schema file [http://schemas.opengis.net/gml/3.2.1/gmlBase.xsd](http://schemas.opengis.net/gml/3.2.1/gmlBase.xsd)

On line 79 there is an attribute with name "owns" which appears to be duplicated (or maybe this schema is imported several times, dunno. Tried using episodes without success).

I tried to rename it using bindings

The result is that 'owns' is renamed to OwnershipAttributeGroupOwns and that is also duplicated.
