I don't know if this should be taken to an sl4-flare, list, but...
If Sally is a human and a quakegunner (or a groud soldier),
wouldn't you want something like this (being extra verbose):
<quantity:number> 2 </quantity:number>
<quantity:number> 1 </quantity:number>
You can still collect all the "arms" and sort them out later or
treat them all as "arms".
Also Schema have nice notions for limiting, say, how many of something
you want (an octopus can have 0 to 8 tentacles). You can also say
Sally has two hands. One is of type lefthand the other is of type
righthand. Kind of like invariants if and when you want them for
(ok, maybe this is getting way too detailed and these things should
be decided later).
