Re: debugging XSLT in Firefox

Firebug is a Firefox Javascript debugger. I looked into why it fails
for XSLT.  Seems like the problem is that XSLT does not signal 
DOMContentLoaded, a known bug.  (See 
http://code.google.com/p/fbug/issues/detail?id=130)

Does XSLT signal other events, similar to nsIWebProgressListener?

Are there interfaces to probe the state of the transformation?

Is there someone interested in XSLT who would like help extending 
Firebug to support it better?
