Detention centres for rejected asylum seekers

“halfway houses” for inmates near release

These are already documented as prison=pre-release
prison:for is discouraged, which I understand. I don’t see why we couldn’t use ; in prison=* where needed
For gender, I’ve used capacity:male etc. Of course then you need to have data about capacity, and not just know the yes/no value. But the prison key page already mentions prison:age as an option, we could use prison:male etc as keys as well
