> Following situation:
> 1) resource includes attribute xyz
> 2) No read-handler is registered for xyz (i.e. default read semantic  Resource.getModel().get("xyz") is to be used)
> 3) Poorly coded "add" handler for the resource doesn't call model.get("xyz") for some reason.
> The effect of this is the read-resource result will not include "xyz" => undefined in the output. Nothing for xyz will appear at all, hiding the existence of the attribute from the caller.
> The read-resource handler can deal with a check in its loop through the AttributeAccess registration for the "no read-handler" case. (This check is already there; an 'else' clause is needed.) If no read-handler, see if there is an entry in the directAttributes map for the attribute; if  not, add one with a value of new ModelNode().
