I noticed a problem with the tag memorial=war_memorial.
A building, monument, statue or other edifice to celebrate a war or victory, or (predominating in modern times) to commemorate those who died or were injured in a war.
If you want to add it to a building there’s no problem, but what if you want to add it to a plaque or statue that are also values of memorial=*?
I noticed is a problem for some user, someone tagged an element as
See Talk:Key:memorial - OpenStreetMap Wiki — war_memorial=yes is mentioned. I prefer using something in the lines of subject=, and memorial:conflict= (=yes might be valid since it’s strangely not in freeform text) directly.
memorial_1= is definitely not the solution. Duplicating memorial= in war_memorial= isn’t convenient.
We could start with mentioning it in the Wiki at least as a way to not loose information when the memorial can be described with another value such a statue, plaque, stone ecc.
