Indeed, though RFC2622 allows only address prefixes, several registries,
including the RIPE Database, allow aut-num and as-set to be part of the
"members:" attribute. RAToolset uses this information to expand such
members into route objects (=> prefixes), whose origins are presented by
aut-num's and as-set's.

Yes, "members:" attribute lists prefixes that may not correspond to the
existing rote objects. To make a route object a member of a set there is
another mechanism - to include them by reference ("mbrs-by-ref:"
attribute).
