Right! I was going to do something like that to make DTC's compatible with the
new USS datatypes. Instead of SBH there should be a dedicated "registrar"
interface capable of handling both directory and non-directory data types.

Interesting, yeah, I agree a registrar that handles this logic would be best
(likely accessed via the SyncService (or SyncClient). I'll update the comment
for now to mention that.
