Generate object model out of RelaxNG schema with RNGOM - how to start?

Question

I want to generate an object model out of an RelaxNG Schema.

Therefore I want to use the RNGOM Object Model/Parser (mainly because I could not find any alternative - although I don't even care about the language the parser is written in/generates). Now that I checked out the RNGOM source from SVN, I don't have ANY idea how to use RNGOM, since there is not any piece of information out there about the usage.

A useful hint how to start with RNGOM - a link, example, or any description which saves me from having to read understand the whole source code of RNGOM - will be awarded as an answer. Even better would be a simple example how to use the parser to generate an Object model out of an RNG file.

I want to generate Java classes out of the following RelaxNG Schema:

I found out that the Glassfish guys are using rngom to generate the same object model I need, but I could not yet find out how they are using rngom.

Answer 1

A way to proceed could be to :

1. use jing to convert from Relax NG to XML Schema (see here)
2. use more common tools to generate classes (e.g. JaxB).
