(This is not the CBOR encoding, but the COMI encoding of keys in URIs.) > For the XML and JSON encodings, all definitions lead to the > same on-the-wire representation, hence the difference is more an > implementation detail.

Well, if the equivalence expectation that I was trying to describe actually is ingrained, then whoever designs an encoding (COMI for its URI encoding included) needs to respect it. That would be important to know.
