Alex - 

Depends on the nature of the error...  In cases of overclaiming,
the current validation algorithm could result in "Invalid".  This
could happen, for example, if major ISP were to initiate transfer
of some number resources to their business unit in another region,
and then fail locally to swing to certs with the reduced resource 
list in a timely manner...  All of the remaining prefixes in the
existing cert would be deemed "invalid" and that could easily result
in some very significant disruption for those validating w/RPKI.
(i.e. as noted in <draft-ietf-sidr-rpki-validation-reconsidered-00>)
