XSL History

I have difficulties to figure out what happened between two
recommendations of XSL. 
http://www.w3.org/TR/xslt
 and
http://www.w3.org/TR/xsl11/
I had found some histrorical informations here:
http://www.softwareag.com/xml/Techn_Links/xslt_book/31290105.htm
http://www.w3.org/Style/XSL/OldStuff.html#OldNews
http://www.dpawson.co.uk/xsl/sect1/history.html
But contents does not cover the period between those two recommendations
I will be thankfull for any hints about historical information of that
period. 

Thanks
