[Announce] Koala XML activities

Hello,

 I am please to announce a new XML service on the Web.
  http://koala.inria.fr:8080/

 The goal of the Koala XML services is to show our
current work on XML.
 Current services are :

 - an XML validation service. This is my own work.
the current version has some troubles with entities.

 - an XSL engine by Jeremy Calles.
the current version doesn't support formatting objects 
yet. This web service can be invoked directly by the
XSLOnline Java program (see attachment).

 Hope you will find this helpful,

Jeremy Calles and Philippe Le Hegaret.

Have fun with Koalas! :-)
