[XSCH] further updates + lock to jeff

Hi Jeff

I have made a few more changes today.
In addition to the tidying up of the references and the change log, I 
also noted that Ashok was reporting that I had misunderstood XPath F&0 
rules for anyURI and have changed example 3L in the xpath version 
accordingly.

If you wish to edit directly the version you should edit is

http://www.w3.org/2001/sw/BestPractices/XSCH/xsch-sw/Overview.html

in the directory xsch-sw-20051027 you will find some XSLT that makes the 
other versions (XSLT 2.0). I use saxon8 available from sourceforge viz:

java -jar saxon8.jar Overview.html delete-change.xsl > both.html
java -jar saxon8.jar Overview.html derive-delete-change.xsl > derive.html
java -jar saxon8.jar Overview.html xpath-delete-change.xsl > xpath.html
