Comment (by karsten):

 Adding a `@type` annotation for detached signatures sounds reasonable.

 But I'm less clear about the other three. A status entry is not a
 descriptor. It is ''part'' of another descriptor. In Metrics Library we
 have `NetworkStatusEntry` for status entry, but it's explicitly marked as
 not being a descriptor type of its own.

 Wouldn't it be sufficient to pass the `@type` annotation of the network
 status containing the status entry to Stem?

 Asked differently, if we make the status entry a descriptor type of its
 own, why would we not do the same with `dir-source` entries
 (`DirSourceEntry` in Metrics Library), `directory-signature` entries
 (`DirectorySignature` in Metrics Library)? (I'm not suggesting we do this,
 but what would we tell somebody suggesting this after defining descriptor
 types for the various status entries?)
