Question about unique powers

[Sir Giles]

I was looking at Call to Arms: 5% Defense bonus Aura to pets and Edict of the Master: 5% Defense bonus aura to pets, both if they are within 40' radius of you.  They both are unique, so I understand you can only slot them once, but can you also slot both of them, so that they stack there buffs?  Mids' planner shows that you can.  It seems that arguments can go both ways, since they seem to be the same buff, just from different sources.  I just wanted to verify that you can use them both, or if they are like the +Stealth Io's.
Thanks,

[Aggelakis]

Yes, you can slot both of the pet aura IOs.

Thanks for the quick reply.
