Shouldn't we add some flags to REP_META_CONTEXT, for client to be insure, is
returned string a direct context name or some kind of wildcard? Just a flags

reserved.
I think it should be up to the metadata context namespace definition to
define which syntax represents a direct context name and which
represents a wildcard (if the latter are supported).
A client which doesn't know what a given metadata context implements
can't reasonably ask for information from that context anyway (since
then the client wouldn't know what to do with the returned information),
so it doesn't help much to add a flag here.
