[Jslib] Re: Advice wanted about RDF / XML

[Mike Potter]

The .zip file available from 
http://jslib.mozdev.org/downloads/index.html doesn't contain an rdf 
directory, it only has one rdf.js file in the io section.
I downloaded the rdf/ directory from CVS (luckily there's only a few 
files :) ) but it would be good to update that .zip file.
