RELAX NG Schema for NETCONF
Here is a RELAX NG schema for the NETCONF protocol.
It's not any shorter than the XSD that appears in the draft,
but it's somewhat easier to understand at first glance (imho).
The protocol examples in the -04 draft have all been validated
against this schema.
I will send the compact form of this schema in another message.
thanks,
Rob
