13760	Option to create subgroups/categories in validator	naoliv	team	"Could we have a way to create subgroups/categories in the validator messages?

For example, with this:

{{{
#!mapcss
node[A] {
        throwError: tr(""test 1"");
        group: tr(""Category"");
}

node[B] {
        throwError: tr(""test 2"");
        group: tr(""Category"");
}
}}}

We get this:

While I would expect to have a general `Category` with `test 1` and `test 2` inside it (ie, `group` is concatenating group's tr + throw's tr, while I want to have them in 2 different levels)
