Ouch.

I would have said the breakage is clearly on the XML side, except that
we have the same problem between, say, integer and decimal64.

I think the breakage we really need to avoid is where XML can tell the
types apart and the CBOR mapping cannot.  Is there such a case?

No, I think the problems are with XML.
There are a few derived types like "xpath1.0" in ietf-yang-types.yang
that rely on prefix to namespace mappings that cannot be represented in CBOR,
but I think the base types are OK.



Grüße, Carsten
