CA setting in each certificate on the chain is correct. As a side- effect always do the following basic checks on extensions, not just when there's an associated purpose to the check: - if there is an unhandled critical extension (unless the user has chosen to ignore this fault) - if the path length has been exceeded (if one is set at all) - that certain extensions fit the associated purpose (if one has been given)
