Option to create subgroups/categories in validator

[naoliv]

Could we have a way to create subgroups/categories in the validator messages?

For example, with this:

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)

After #13798 gets fixed, I would still like, if possible, to have a way to create subcategories.
For example, with group: tr("A/B"); we could have a tree like:

Warning:
    |-- A
        |-- B
            * object foo
            * object bar
            * object etc

Closed as duplicate of #13798.

Your example works now. Was fixed in r11127.
