Metadata editor should display only the attributes for gml:unitsSystem as according to xsd can´t have content

According to xsd, the element `gml:unitsSystem` can't have content http://www.datypic.com/sc/niem21/e-gml32_unitsSystem-1.html

But the metadata editor displays an input text to edit the value.


The issue identifies the metadata editor and the gml:unitsSystem element but names no source file or test. Start by locating the editor handling for this element and compare its displayed controls with the referenced XSD behavior; done means the content input is no longer shown and the appropriate attributes remain editable.
