schemaLocation not pointing to valid path

I guess XSD files were originally placed at /xsd/. Should them be moved back or perhaps placed under /schema/ (possibly followed by subdirectories to classify by schema type)?

Also noticed that https://rs.gbif.org/schema/xml.xsd fails to display on FF and Chrome, whereas the other schemas work fine. This URL is pointed by tdwg_dwc_text.xsd.
