> Given that we are locked down to using only XML for configuration and most of the administrators
need to manage it by themselves (unless a tool that manages for you is used), it would be
good to also validate the provided config XML (*-site.xml) files with a tool like {{xmllint}}
or maybe Xerces somehow, when running a command or (at least) when starting up daemons.
> We should use this only if a relevant tool is available, and optionally be silent if
the env. requests.
