It's invalid, as <prop> should contain a child element specifying the 
property.

Thus, it seems that status 422 makes sense.

Note that 412 has a very specific semantic that doesn't apply here.

And yes, it's unfortunate that there's no really simple way to just get 
the children of a collection; when I needed this, I usually asked for 
DAV:resourcetype, as this is known to exist on every resource, and 
should be cheap to compute.
