11gR2 Cascaded Standby with SYNC and ASYNC

12c has introduced Far Sync as a "product".

In 11gR2 (and 10g) we could implement Cascaded Standby. I am looking for experiences / notes / case studies / gotchas with an 11gR2 architecture that has
(a) "Near" Standby in SYNC mode [preferably running only the
instance and processes without database files ?]
(b) "Far" Standby in ASYNC mode [with the full database]

Support Note 409013.1 has some information but not enough. I couldn't find a Cascaded Standby described in Larry Carpenter's 11g DataGuard Handbook (maybe I haven't put in enough effort in the search).
