A multislot is like an array or list, not like its own template with
subslots. If you want a slot to contain structured  data, then have
that slot contain another Fact, with its own structure.

Note that this restriction is exactly like java. Java variables have
no structure -- they refer to exactly one thing. If you want a
variable to have structure, you have to make it point to another
object.
