You have documents that would break? Can you point us to them, or
share the relevant details?

How would it break those XSLT engines? The XSLT engines I've seen
don't use HTTP to find the java code or anything, so changing the spec
to say (or suggest) that if you use http://... as a namespace name,
folks should be able to get information about that namespace
on demand by visiting that address won't affect those XSLT
engines whatsoever.

Don't you think it would be convenient if, upon finding
	xmlns:xt="http://www.jclark.com/xt/java"
I could ask "hmm... what's that all about?" by visiting
http://www.jclark.com/xt/java and getting some documentation
and examples and such?

I'm not sure what you mean by "allow you to generate an HTTP uri";
XT allows you to *use* a *particular* HTTP URI to indicate
that you want to call out to java. It doesn't have a mechanism
where you choose a namespace URI and it associates java code
with your choice of namespace URIs somehow.

(see http://www.jclark.com/xml/xt.html for documentation
of the http://www.jclark.com/xt/java namespace, btw)
