I disagree. It's not at all clear from the above description how the
reader will interpret "a/b/c":
(1) namespace: a/b
name: c
(2) namespace: a
name: b/c
(3) throw an exception since the string violates "it can be used once".
The reader as implemented behaves as (1), though it's not clear from
the documentation why this would be preferred above (2) or (3).
