That is good. But what I meant was (in your I-D under discussion) does 
the alternate validation algorithm for a ROA need slightly different wording 
(as compared to that for certificates)? 
Such as:
A ROA is "valid" for a given IP address prefix specified in the ROA, 
if the given IP address prefix is subsumed in the resource extension field 
of the end-entity (EE) certificate (contained within the ROA),
and also subsumed in the resource extension field of all other certificates 
that are contained in a certification path, where the 
construction of this certification path is defined in Section 6 of RFC5280.
