Hi Bryce,
Openxml classes are built from the XSDs. This is something that is seldom done.
Download the full source and look into the maven directory in the
ooxml-schemas.pom and you will see this comment:
<description>XmlBeans generated from the Ecma supplied xsds:
http://www.ecma-international.org/publications/files/ECMA-ST/Office%20Open%20XML%20Part%204%20(DOCX).zip</description>
Apache xmlbeans 2.3.0 is used.
Good luck, someone else will need to help with any deeper detail.
Regards,
Dave
