If a Global Configuration server is to handle local contributions to local configurations, or if subsidiary layers of global configuration servers are to be supported, then a leaf node in the contribution tree might not be an immediate contribution to a GC in that first GC server. In that case, that first GC server must either be notified of the change to the contribution tree, or must delegate component resolution to the next layer down (the subsidiary GC server, or the local configuration server with multiple levels of contributed configurations).

The current draft spec does not address delegated layers of component resolution.
