One vs. two colons with DIR: is an implementation trick to distinguish
between when the directory is being treated as a collection, and when a
single file within the directory is being used.  (I believe this is
specific to DIR: at the moment, and the other collection-enabled cache
types have other ways to distinguish between these cases.)

I thought I had documented this to help alleviate confusion such as yours,
but it looks like maybe that was only in my talk at the EAKC back in
March.
