Yes, and that's perfectly fine :-) I'm just puzzled why Roy thinks it doesn't make sense to reduce validation latency. I'm also wondering what the advantages are to bottom-up validation. It gets really knotty when the leaf records have broken signatures - you have to keep walking up the tree to see if there's an insecure delegation to work out whether to return bogus or insecure.
