If no other instances of this service have been registered, a default
instance of <a href="ServiceInfoFactory.html" title="class in org.eclipse.ecf.osgi.services.remoteserviceadmin"><code>ServiceInfoFactory</code></a> will be used. Note that this default
instance is registered with the lowest possible priority, so that if other

preferred/used over the default. This means that Those wishing to

<a href="../../../discovery/IServiceInfo.html" title="interface in org.eclipse.ecf.discovery"><code>IServiceInfo</code></a> must
