relaxer

I read about Relaxer, the thing that compiles .RNG to Java classes. BBut the website, http://www.relaxer.org/ , is dead. Q1: Is Relaxer alive? Is it real, does it work? Is it reasonable to generate Java classes from .RNG? Q2: Is there a Relaxer for .NET? Is there a tool that generates C# classes from RelaxNG schema? Q3: Is there a Relaxer for Javascript? AND, finally Q4: Is RelaxNG alive? Is it viable? Relevant and useful in the REST/JSON world? Are people still using it or is it going to fade, a good idea that has been dropped? I know that is subjective, but I'd like to know your assessment.
