Oh, may be caused with this "maintenance" resource meta-attribute not
being documented at all in 1.1 line (while it was introduced in 1.1.12
and now we are at 1.1.22):

Again, something we shall rather prevent (undocumented options, not
even in some "experimental" section that would list provisions that
may be changed or disappear again for things in need of some gradual,
multi-release incubation).

Can we agree on some principles likes this?
