[stable since 2013] a lib for loading XML Schema Definition (XSD) files ➜ plus, a tool `makepkg` to code-generate from any *.xsd your Go package with all needed `struct`s to readily `xml.Unmarshal()` documents into, based on the XSD's schema definitions. NOT REALLY MAINTAINED FOR YEARS NOW: try the forks if running into issues.
Invalid Go identifiers were being generated, specifically with the common case of hypenated XSD import names.
