First of all, you should watch your language. Secondly, you shared an article from the PM office that states the area name, which is not the one you mentioned. See: https://pmo.iq/?article=2032. The PM office said منطقة المعامل, not منطقة الحسينية, which proves that the name you are using is neither the one used officially nor the one used by the locals. As a local mapper from Baghdad myself, and I'm pretty sure others will agree, when we hear الحسينية, we think of the area up north of the city. The one you are referring to is called المعامل, and that is it.    
    
The marketplace having the name is not a valid argument, as there are tons of markets with the same name all around Iraq in areas that do not share the name of the market.    
    
I'm going to correct the name to the one from the PM office, and you should not edit it to something else without prior discussion.
