Because of a mistake of my own, I originally posted this XPath 2.0 related 
message in www-xpath-comments@w3.org , when it should have been posted here.

Former messages and one response were archived as:
http://lists.w3.org/Archives/Public/www-xpath-comments/2008JanMar/0000.html
http://lists.w3.org/Archives/Public/www-xpath-comments/2008JanMar/0001.html

Sorry for the inconvenience.

Javier Godoy
