Hello, I'm no longer at the W3C and these questions are probably best taken 
on by the "XML Security Specifications Maintenance Working Group" [1] 
and "site-policy" regarding copyright issues, but I provide some thoughts

I wrote the RNG as a personal exercise but in any case I think it would be 
covered by the software license [2], just like the XML Schema version, 
which does permit derivative works under certain conditions.
