In the bestiary for the new D&D Next playtest packets, some creatures look as though they get multiple attacks per round.
e.g.: An owl bear gets Melee Attack: Claws +5/+5 (etc.) and Bite +5 (etc.) along with a special power says that if both claw attacks hit, then extra damage is done.
However, the basic rules don't seem to cover this situation. I can't tell if the owlbear is able to use both claws AND bite in one action, or if it can only use one claw OR a bite, or 2 claws OR A bite.
So, do monsters get multiple attacks per action? And what are the rules for the owl bear, or other monsters that have a +x/+x description for an attack?
One possible way to answer this question would be to explain how this worked in earlier editions of D&D. If you can tell from the rules test how this is supposed to work, that would be a better answer.
