We have more or less finished posting the first 
version of our XSLT tutorial, XSLT by Example:
http://www.objectsbydesign.com/projects/xslt/xslt_by_example.html

The tuturial is a companion set of pages to our 
XMI to HTML pages, which have also been fully revised 
along with the XSLT style sheet.

Suggestions welcome.
Hope it helps.
