Generate Java SPDX Model Classes from XML XSD file.

The project aims at generating the Java Model Classes for proposed XML XSD files of repositories. This involves mapping the elements of XML Schema to members of a java class using the tool, which would enable conversion. Conversion is important for the sharing capability of the specifications. Importing packages and customization of tools enabled modification of generated classes. The generated classes would be used as part of a re-designed Java tool for SPDX. This could be used by the organization, whenever required, to map XSD to java classes.
