> 1.	Step size?

This one is kind of funny.  When you ask for a list of terms, you kind
of
think that they will be adjacent term.  But, if you want, for instance,
every other term, then you need to specify a step size.  Every term
would be
a step size of 1 (the default).  Every other term would be a step size
of 2.

From the standard (with my comments in parens):
0 - Success
1 - Partial-1: Not all of the expected entries can be returned because
the
operation was terminated by access control (you aren't permitted to see
these terms)
2 - Partial-2: Not all of the expected entries will fit in the response
message (the resulting message is too big.  You probably asked for way
too
many terms.)
3 - Partial-3: Not all of the expected entries can be returned because
the
operation was terminated by resource-control, at origin request. (You
asked
for the scan to be stopped.)
4 - Partial-4: Not all of the expected entries can be returned because
the
operation was terminated by resource-control, at the target.  (The
server
decided that it had worked to hard on this already.)
5 - Partial-5: Not all of the expected entries can be returned because
the
term-list contains fewer entries (from either the low end, high end, or
both
ends of the term list) than the number of terms requested.  (The index
didn't have as many terms as you asked for.)
6 - Failure: None of the expected entries can be returned.  One or more
non-surrogate diagnostics is returned.


> 3.	Default diagnostic?

A diagnostic from the default diagnostic set.  For extensibility, there
is a
way to create your own diagnostic messages.  This is just telling you
that
it is one of the standard diagnostics.

In your case, diagnostic 114 means "Unsupported Use attribute" and the
extra
info of 1016 is the Use attribute that the server didn't like.

So, the upshot of the response you got was that the server doesn't
support
browse on the "Any" index.

Hope this helps!
