You are correct; the standard does not say much on error resilience topic.
A quick search on the word "loss" led me to 8.2.5.2 and page 90
(redundant_pic_cnt).
Anyhow, your reply did help me rethink about my problem.  I think even
loss of a whole frame should be reconstructable with help of motion
vectors of preceeding and succeeding frames.
