[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.
Trying to use the library for http://www.accessdata.fda.gov/spl/schema/spl.xsd
I've been able to successfully get the generated go code, but on compiling, it complains about recursive structs and then stops.
