+// mdsclient - friendly interface to CDSA MDS API
+//
+// It is useful to think of the mdsclient interface as "slightly below" the
+// rest of the cdsa_client layer. It does not actually call into CSSM (we
+// consider MDS as a separate facility, "slightly lower" than CSSM as well).
+// This means that you can use mdsclient without creating a binary dependency
+// on CSSM, and thus Security.framework.
