Review comment:
The URN represents the unique identifier in the "semantic meaning" space of
the counter. So saying that this is a user counter and that there are many
types makes sense to me.

Review comment:
The problematic type is `string`:
Is `sum` the same as concat? (if so, this will grow to be huge very quickly
also making distribution pointless)
Is min/max/top_n/bottom_n based upon lexicographical ordering? (if so, case
sensitive/insensitive/...)
`string` only makes sense with latest and if we wanted to define any of the
other ones I think it would be better to use terms like `case_insensitive_max`.
