COMMENT:
----------------------------------------------------------------------

In sec 3.1 it says the AS SHOULD reject req_cnf if the key is symmetric. But in
Sec 5 it presents a totally reasonable use case where the C and RS hold a
previously established (symmetric?) key.  These observations are somewhat
contradictory. Should 3.1 include a qualifier. Would the AS know about this key
a priori so that it can ignore the recommendation? If not, how can this be done
safely?
