I absolutely agree. Another way of saying this is that the stream of SAX
callbacks coming from parsing/decoding an encoding of ASN.1 (BER, PER,
EXTENDED-XER) has to be exactly the same stream, for a given schema and a
given instance, regardless of the encoding rules in use (BER, PER,
EXTENDED-XER), and has to be the same stream as would be generated by a
"normal" SAX parser parsing the XML document. It must be possible to
replace a normal SAX parser used by an application with an ASN.1
parser/decoder for either XML or binary encodings with minimum changes to
the application code. This will give us the interoperability we need
between the two worlds.
