Hi, I agree with this report.
The clarification should have been included. CA certificates were intended - RPKI object retrieval is irrelevant in the context of the EE certificates in RPKI signed objects. And as Job pointed out the addition of the access description would not be allowed there. Speaking for myself only I have used the term "resource certificate" in the RPKI colloquially to refer specifically to RPKI CA certificates. It seems that leaked into this specification unintentionally.
