   _Be sure not to overwrite the `.gitignore` already in the "empty" `xsd` folder, as we do NOT want to keep the XSDs in this repo!_

     1. Keep an eye out especially for any source code generated under an `ns` package path, as this means a specific XSD was not assigned a package name.
 6. If everything looks good, create a PR, noting which version of the ORCID XSDs you used to update the Java source code (e.g. either a specific release number or `master` of a given date)
