request Wagn support XML and XSLT+issues

I hope Wagn can support  XML/XSLT, such as Flux CMS,  a Web Content Management System based on [PHP 5][http://ch.php.net/] and [Popoon][http://popoon.org/], and Daisy, a CMS based on PHP and [Apache Cocoon][http://cocoon.apache.org/].
Thanks a lot! This is my first post. Also this is my try of Wagn. --tonyliuh
