So, do we know enough that the customkeymanage part isn't necessary for
any known normal use of xml signing, I mean if we disable it, or build
against a system version that doesn't have it, that the uses we do know
about continue to work. I could live with that for at least distro
builds to flush out if there is some useful purpose to it.
