Hi!

I am trying out some sample documents in XHTML 2 that I would like to
check with the Relax NG schema available at the W3C website [1].

Where can I find the actual Relax NG files? After some digging I found
[2] but those files seem to be older than what is available at [1]?

Should I copy and paste the Relax NG source from the HTML pages at [1]
to get the latest version?

Regards,

Peter
