Hello,

Your latest 100 edits have the same changeset title and no source.  Can you please source your edits when uploading?  (And please consider grouping your edits per area.)

About this change here: I cannot find official data with "21004E" as the official code for this part.

The closest I could find was this open data feed, where all sub-municipalities keep the same code as the parent municipality, i.e. 21004.

https://opendata.bruxelles.be/explore/dataset/codes-ins-nis-postaux-belgique/table/?disjunctive.postal_code&disjunctive.refnis_code&disjunctive.gemeentenaam&disjunctive.nom_commune&disjunctive.code_ins_region&disjunctive.region_fr&disjunctive.region_nl&disjunctive.region_en&sort=refnis_code

Also, is the "ref:INS" tag documented somewhere, in particular how it should apply to objects with different admin_level?  Could you please explain why you are adding this tag to objects in the database?

Looking forward to your reply.  Thanks.
