9631	Validate population key	naoliv	team	"It seems that JOSM doesn't validate the population key. Anything can be entered as value and no warning is given.
JOSM should accept only integer numbers as value.

Something like this, maybe:

{{{
#!rule
*[population !~ /^[0-9]+$/ ] {
        throwWarning: tr(""{0} must be an integer value"", ""{0.key}"");
}
}}}"	enhancement	closed	normal	14.02	Core validator		fixed
