Do you have to deal with XSD in your life?

If you do how do you go about doing it? I attempted to use https://github.com/metaleap/go-xsd but the XSD in question is much to large and unwieldy and potentially not super well formed (its from a 3rd party company), I have been struggling for a few days trying to make a simplified XSD to go struct parser, but now I am wondering if i should take a different approach.

Do any of you guys have unwieldy XSD experience?
