Interesting. It seems that what I needed basically works at the moment
in that I can do.
node = tuscanyRuntime.createNode("uri:" + domainName);
node.getEndpointRegistry().getEndpoints().toString();
And expect to get any endpoints that are currently in the domain. I.e
the domain info is available even though I haven't "started" the node.
If this had not been the case I could of course have attacked the
registry directly however as you are adding code to do things like
construct the domain composite it seems useful to be able to re-use
that code.

At the moment I was just wanting to see what's there. I'm interested
in how the domain artifacts might map to URIs / URLs. Not interested
in actually invoking anything at the moment.
