[Ietf-calsify] What's the status of xCal?

I'm currently implementing an export function in KOrganizer that uses XSLT 
transformations to create easier output in several formats and even allows 
XSL-FO to be used for printing. For this, I need an intermediary XML format, 
and xCalendar comes in quite handy here. 

However, I could only find expired drafts on the net (with various different 
namespace URIs used, so I'm not sure which is the current one). So what's the 
status of xCal?
I found the draft
using "urn:ietf:params:xml:ns:xcal", but not using the namespace prefix 
consistently, so most of the elements are NOT in that namespace :-(
(Older drafts use the namespace "http://ietf.org/rfc/rfcXXXX.txt", and they 
employ the xCal: prefix consistently).
I also found the older calsch-many, but that's obviously a deprecated draft.

Of course, once I have implemented several xsl stylesheets (maybe even to 
xsl-fo for printing/exporting a calendar to PDF in various layouts), these 
transformations won't be restricted to KOrganizer, but can be used with any 
xCalendar file produced by any application that is able to export to 
xCalendar (which are not many currently...).

So is there any decision on the XML representation of iCal? Or is this dead 
and I need to come up with my own XML and other applications won't be able to 
use my stylesheets, because we don't have a standardized XML representation, 
only self-cooked ones?
