If I understand correctly, it works only for `$xavp(key)`, not for `$xavp(key1=>key2)`, right?
Also, I wonder if it is not better to enhance the `$cnt(...)` variable for this purpose, now it is for avps.
Yes… it works only with a single key. This is all I needed.
But you’re right, it would be better to also handle sub-keys. That was a quick PR since I already had the code. Feel free to discard it. :)
