Yes, the testing I did confirms that BIND performs correctly when it 
encounters a DS in the parent zone that points to a key in the child 
zone whose alg is unknown, it simply treats the child zone as insecure. 
  Olafur is correct in that org.br is handled (correctly) in this manner 
by BIND (thanks for the example).

Not sure what version of unbound Stephane was using; the one I have is 
1.2.1 and it supports NSEC3.  E.g. satellite.dnslab.jp resolves and 
validates correctly using the DLV.
