+  - Translate between old "myrpki" XML and current IETF standards
+  - track out-of-band-setup protocol XML.  Well, partially.  Much of
+  - the old protocol is either irrelevant or can't be translated due
+  - to embedded signatures, but the subset that other implementations
+  - implement is small enough that we can fake something workable.
