I have an objection to this "translation" work.
You will make all kinds of assumptions about data organization
and data naming, and I'm not sure what people are supposed
to do with the XSDs.

The term "XSD translation" is misleading.
The XML on the wire is what is at stake here.
The smidump translation of a MIB has SNMP operations
built into it.  Is this work supposed to produce
a standard way to send an SNMP PDU over any protocol
designed to encode SNMP PDUs in XML?  Why do we need this?

Is the charter going to state that the XSD translation will
be suitable for use for any particular protocol?
NETCONF needs to standardize XML data organization,
namespace usage, and Xpath-based data naming.
Is this translation going to be compatible with that standard
when it eventually comes out?

I would like the charter to be clear on the purpose of this work item,
and what 'protocols' are signed up to use it.
