description:
An optional namespace, underneath which to list namespaces.
If not provided or empty, all top-level namespaces should be
listed.
- If parent is a multipart namespace, the parts must be separated by
the unit separator (`0x1F`) byte.
+ If parent is a multipart namespace, the parts should be separated
by the namespace separator as
+ indicated via the /config override `rest-namespace-separator`,
which defaults to the unit separator (`0x1F`) byte.
+ To be compatible with older clients, servers have to use `0x1F` as
a fallback even when advertising a different
+ namespace separator to clients.
Review Comment:
My point is that it is not clear what is "fallback" in this case. I propose
to treat both old and new separators equally (always respect both, even when
intermixed)
