I am on the 6th chapter of the book RELAX NG in the beginning of the
chapter we r advised to download the XMLDistilled's Xmlde editor(www.xmldistilled.com) to validates against an rnc schema , as the topology shematron validator will not support it.
  but a visit of the website says "the site is temporarily unavailable".Could any one direct me to a rnc schema validator on any other site.

Did you have any success with finding anything?

I've just got to this point now, and its appears XML Distilled web site is no longer available. :(

Try the Relax NG site for other validators. http://relaxng.org/#validators
