It is about identity and globally unique identifier assigned with some
identity. http:// URLs are automatically assigned to persons owning
given URL space (controlling server under given domain and URL path).
That is very convenient for anyone that wants his own XML namespace
-- I guess it is much easier for an average Joe to get his http://
namespace (just get some HTTP hosting) than to get hist own URN prefix
(does URN work this way? I am not sure). And it won't make sense to
assign URN for Joe if the XML namespace will be just temporary (e.g.
some testing or prototyping).

For JSF things are simpler, of course. But http URIs may be still
convenient. Just add the HTTP redirection from the namespace URIs to the
XEPs URLs and it will be trivial to find a documentation for a new JSF
protocol. For URNs some additional registry will be required.
