Michael,

To paraphrase your own message of 11/11,

Can you please formulate what exactly is the problem using more concrete terms?
What is the problem with asn06 syntax that Sandro has used and how does BNF resolve that?

I do not understand your objection nor your use of the terms "useless" and "harmful" here.

Thanks,
Chris
