RE: Difference between get and get-config

["McDonald, Ira" <imcdonald@sharplabs.com>]

Hi,

I find it disturbing (but not surprising) that Andy
and Martin suggested two different errors (and two
different underlying reasons).  

The underspecified behavior of Netconf for various 
error conditions will probably be a source of very
widely divergent behavior on the part of Netconf
clients - who apparently should expect just about
anything in responses and somehow always gracefully 
cope with it.

Cheers,
- Ira

This is what <get-config> and <copy-config> does

Yes -- an access-failed error because you are attempting
to write to read-only data
