Hello. I have a few questions/remarks about the addresses here:

addr:country tags should only contain the 2-letter code. 

Building numbers (عمارة رقم ) should not be part of the addr:housenumber tag.

What does addr:daïra mean?

Why are there several places with addr:housenumber=0 ?

addr:city seems to be tagged in an inconsistent way: I found TAGHZOUT, Taghzout ⵜⴰⵖⵣⵓⵜ تغزوت and تغزوت. Which one is correct?
