Maybe the repository should have been constructed in LDAP with a manifest
object there to confirm the ldap search returned all the roa objects.

I am, and still, remain uncomfortable about RPKI using filename extensions
as the only mechanism to select the validation regime. It might be a
flippant statement but even Microsoft office can tell a word document from
an excel document without the extension.

Perhaps Randy's terse statement about starting again with TLVs isn't
actually bad advice given that getting stuff from a repository isn't
actually a specific question/answer model.

Cheers
Terry
