The current specification implies that a context cx--.foo.bar.baz. may have top-level or nth-level assertions signed directly by the key delegated to foo.bar.baz; does foo.bar.baz in context . explicitly need to delegate to . in context cx--.foo.bar.baz? Probably, to make it explicit that a given context exists.
This should just work, I think -- it's clear that . in cx--.whatever should be signed with .whatever's key.
