wouldn't it make more sense to make the doc generation include that
information automatically? a format name with -list at the end always
means that it is a \0 or ,;\s separated list of values of the "child"
format.. so instead of <string>, this could print

<lxc-ip-with-ll-iface>[, <lxc-ip-with-ll-iface>[, ..]]

for example, with all the required information already available in the
schema..
