requirements that already exist to accommodate key rollover and alg 
transition for the RPKI. We have a SIDR doc describing both key 
rollover,

I find your last sentence above confusing.  I would say that the 
BGPSEC protocol will have to define how it deals with alg changes for 
the signed objects it defines, with key changes for RPKI certs, with 
alg changes for all RPKI objects, and with format changes for RPKI 
objects and for its own objects.
